I'm doing transient thermal analysis in ANSYS. I tried to simulate the fire resistance behavior of simple beam protected by intumescent coating, the temperature input I get1 from the experiment data.
My problem is, I always get notification "An internal solution magnitude limit was exceeded..."
I have tried to repair and adjust the mesh, step, and other settings, but it didn't work out.
Could anyone please help me to solve this problem?
In case of you want to see my model, hereby I the link to access the model.

Hi, as attached is thepicture of connection that makes the error "BONDED or NO SEPARATION type required for this contact configuration" appears. It is under Frictional, which I think is the problem. I read from a few articals saying Normal Langrange should be used for non-linear contacts. But when I use Normal Langrange, the error "An internal solution magnitude limit was exceeded. (Node Number 24274, Body SYS-1\Beam (Extracted Profile1), DOF UZ) Please check your Environment for inappropriate load values or insufficient supports. You may select the offending object and/or geometry via RMB on this warning in the Messages window. Please see the Troubleshooting section of the Help System for more information." returns. I am unable to use Normal Lagrange so far.

I have looked at the Newton-Raphson residual forces and one washer has most of the residual forces but I am not sure whether this is a red herring and the internal magnitude limit is being exceeded elsewhere.
Each joint probe shows the magnitude and direction of the force at each probe. The results show that there's a range from 200 N to a whopping 1500 N. Fortunately, the 1500 N force is in the center and the flexure mount forces have a value around 400 N.s
The easiest way to check this out is to go into a model and insert a force into your model. Go ahead and pick the geometry. In the Details for the force, click on the magnitude cell and you will see a little drop-down menu triangle:
The prevalence of the elderly population increased in the 20th century, as described in the World Health Organization 2004 Annual Report. The use of tilted implants parallel to the anterior wall of the maxillary sinus or the mental foramen/inferior alveolar nerve has been proposed for the treatment of the atrophic edentulous ridge. The aim of this study was to evaluate stress and strain magnitude in tapered and cylindrical surrounding bones. A 3D finite element model of an edentulous mandible was constructed. Two models of implants were used: cylindrical and tapered BEGO Semados RI Implants. Four implants were inserted between the bilateral mental foramen according to All-on-Four concept, and a mandibular bar was designed to use with the All-on-Four bar supported models. A vertical and 30 degree vertical load of 100 N was applied to both cylindrical and tapered implants models. Strain and stress were analyzed with ANSYS software (ANSYS R18.0). The maximum stress and strain were applied in all axes for the posterior man-dibular areas in the crestal region of the bone, and for the anterior areas at the intraosseous contact site. Also, the stress and strain of the bone under force in all axes in all areas for tapered implants is less compared to that for cylindrical implants. We found that the highest rate of bone resorption occurs in the posterior areas near the junction of the fixture with the abutment of implant, and in the anterior areas near the end of the fixture of implant. Still, more research on the subject is needed.
The upper panel shows a representative WSS Map from an aorta with a coarctation. (A) There is low magnitude oscillatory WSS in the downstream region and high unidirectional WSS in the upstream region. The lower images show representative confocal images (63x) from en face mounted aortas stained for either VCAM-1 (B and C) or superoxide (D and E). The images on the left (B and D) were taken from the upstream region while the images on the right (C and E) were taken from the downstream region. (To see this illustration in color the reader is referred to the web version of this article at www.liebertonline.com/ars).
These material properties along with their magnitude are also assigned with a number. So that we can later relate elements with their properties as there can be many elements having different properties.
Along with the results in contour form, there is a scale which used to read results. ANSYS use different colors to define and show different sections of element with varying property. Part of beam with same color shows that it has the same magnitude of that property. Notice the abrupt change in beam even after we have defined it as elastic. This is so because it has a very poor nodal resolution. If many hundreds of nodes were defined between these nodes, the result could be very changed. But here, the objective is to demonstrate the use of APDL for analyzing such situations.

Three sides ofthe trapezoid are formed by the element (one side) and lines at nodesI and J of length proportional to the item magnitude and displayednormal to the element and the viewing direction (the two parallelsides).
Abstract: This paper presents the modelling and vibration control of the tetrahedral space frame. The tetrahedral frame is a structure that is used in precision machining applications. When machining at a high precision requirement, structural vibration is of the utmost concern. This research develops finite element models using ANSYS and Matlab that can be used to implement a positive position feedback controller. In order to control and reduce the vibration magnitude, collocated piezoelectric actuators and sensors are placed at the optimal positions on the tetrahedral space frame. ANSYS is used to conduct a modal analysis on the structure to obtain the mode shapes, which determines the weakest positions and critical vibration modes under certain machining conditions. In Matlab, a finite element model is created which uses Timoshenkos beam elements and it is further converted to state-space allowing the model to be controlled using programme simulations. A positive position feedback controller is chosen due to its non-sensitivity to spillover effects.
The FEM-Parameterized Synchronous Machine block uses fluxlinkage that you must calculate by using an external finite element (FE) tool. The blockuses the A-phase flux linkage, which is a four-dimensional table thatdepends on the stator current magnitude, stator current phase advance, field windingcurrent, and rotor angle. The block derives the field winding flux linkage bycalculating the D-axis flux linkage from theA-phase, B-phase, and C-phaseflux linkages and by subtracting the flux linkage when the field current is zero.
Nominal values provide a way to specify the expected magnitude of a variable in a model. Using system scaling based on nominal values increases the simulation robustness. You can specify nominal values using different sources, including the Nominal Values section in the block dialog box or Property Inspector. For more information, see System Scaling by Nominal Values.
Row vector of current magnitudes at which the block tabulates the fluxlinkage. The first element must be 0. The secondcurrent value must be small relative to the current values at whichmagnetic saturation begins to occur. This restriction is necessarybecause the derived flux partial derivatives are ill-defined at zerocurrent, and the block calculates them at this first nonzero currentinstead.

Reactor performance of confined jet mixers for continuous hydrothermal flow synthesis of nanomaterials is investigated for the purpose of scale-up from laboratory scale to pilot-plant scale. Computational fluid dynamics (CFD) models were applied to simulate hydrothermal fluid flow, mixing and heat transfer behaviours in the reactors at different volumetric scale-up ratios (up to 26 times). The distributions of flow and heat transfer variables were obtained using ANSYS Fluent with the tracer concentration profiles being simulated via solving the species equations. The predicted temperature distributions under various volumetric scale-up ratios were compared with the available experimental data, and good agreements reached. The mixing between supercritical water jet and precursor stream with different scale-up ratios was examined in detail to identify the effect of scale-up ratios on hydrodynamic and thermodynamic features. The findings indicate that slightly weaker mixing was observed at the pilot plant scales, but the momentum dominated turbulent flow in the reactors and the same order of magnitude of mixing levels at both laboratory and pilot plant size scales could lead to similar quality nanoparticles to be manufactured under the investigated volumetric scale-up ratios and operating conditions, which is supported by experimental observation from literature.
