*static Abaqus

[Silvina Spindler]

Edit1 : I don't want to use abaqus make utility because I want to build my own postprocessing application based on .NET platform. The lines "odb_initializeAPI();" and "odb_finalizeAPI();" are the lines which should be used if I want to access Abaqus ODB API outside Abaqus CAE. I'm actually following this page from the scripting documentation " :2080/v2016/books/cmd/default.htm?startat=pt05ch10s07.html"

If you have Abaqus on your machine, then you should also have the documentation. The section "Abaqus Scripting User's Guide" contains a section "Using C++ to access an output database." There you can find some examples and the details I've pointed out here. It should be a good starting point for your work.

EDIT: After pointing out that you wish to use the Visual Studio for development and compilation, make sure to check the system requirements for the Abaqus version you are using. Try to use the same Visual Studio C++ compiler as the one used for compiling Abaqus. Simulia is most probably using an older version of the Visual Studio C++ compiler than you are.

Can we think that way:The Time period is the real/physical total deformation time for the static problem and is scaled to 1. And its substep which from Time period/number of increments comes from the sub deformation which is also scaled.

"Statics" usually is defined as meaning that the acceleration of the structure is too small to cause significant inertia forces, i.e. the "mass $\times$ acceleration" terms in the equations of motion can be ignored.

For example in a creep analysis, the amount of creep strain is time-dependent, and may eventually cause structural failure even when there is no change in the external loads. In this type of analysis, time is a real physical quantity, not an arbitrary scale factor between 0 and 1.

Even if the material behaviour is linear, in a coupled thermal - structural analysis the changes in the temperature distribution depending on the thermal conductivity and specific heat of the material are modelled in "real time", and produce corresponding real-time changes in the thermal stress in the structure.

If there is a material non-linearity then the solver will have to converge in small steps towards the solution (using for example the Newton method or line search), but it is not related to the time you are asked to enter.

While the other answers make some good points the only one really addressing the issue is Schneider's response.The time increments in a static problem in abaqus means that the total load, say for example 10 N, is divided into chunks of say 1 N each (if you have 10 substeps), and the software adds 1 N each time the previous substep has converged. This is done because it is easier for the solver to converge with small loads.

Thank you very much for your reply. I aim to create a file for my mesh that includes the locations of the nodes and the connectivity of the elements. I would greatly appreciate your assistance with this.

If you are struggling with license, I'm not 100% sure this will work, but you could try getting the student version of Altair Hypermesh, that might be able to read in ansys .cdb mesh files and export abaqus deck.

Thank you very much for your reply. I cannot find Modal (ABAQUS) in my ANSYS student version. Additionally, I am attempting to right-click on the solution and export NASTRAN. However, when I click on that option, nothing happens. What should I do to export using that option?

I want to know which ones represent the connectivity. For each tetrahedron, there should be only 4 numbers indicating connectivity. I cannot understand this file. Can you help me comprehend it? my goal is to create a file for my mesh contains the location of the nodes and connectivity of the elemnts. I want to use it in CCX solver.
