We supplied an inertia separator to a client. They issued the order and then came back with some further information on the anti-icing system. We were able to run a thermal and fluid flow analysis with SOLIDWORKS Flow Simulation within 24 hours to confirm that the product supplied would work and that the anti-icing would have no hot or cold spots on the separator vanes. This saved us and the customer up to four weeks in external review and 5 to 10K in assessment costs, and kept the project on-time and on-budget.
Candidates who successfully pass this certification have demonstrated the ability to set up, run and examine the results of various types of fluid flow simulation scenarios. They also have demonstrated the ability to interpret the various results available to them in SOLIDWORKS Flow Simulation and an understanding of the basics of finite volume methods.
Aim: The aims of this study were (1) to develop a multimodal intervention according to the NLN Jeffries Simulation Theory planned to improve attitudes and empathy towards older adults in undergraduate nursing students using theoretical contents, age simulation suits, and storytelling of old participants, and (2) to evaluate the influence of the simulation flow on the effectiveness of this intervention in improving attitudes and empathy towards older adults.
Methods: A three-period crossover randomised controlled trial with an experimental group, a control group (that transitions to a delayed experimental group) was conducted on 70 nursing students after the initial 73 were allocated. A multimodal intervention was used that, in addition to geriatric nursing theory, incorporated complex age simulation suit and student-older adult interaction. Pre-test and post-test data were obtained through the Jefferson Scale of Empathy and Kogan's Attitudes towards Older People Scale. Thus, students in the experimental group 1 received the following simulation flow: Geriatric Nursing Theory + Seminar with age simulation suit + student-older adult interaction. The students in the delayed experimental group 2 received this order: Geriatric Nursing Theory +Seminar without Age simulation suit + student-older adult interaction + Age simulation suit.
Results: Statistically significant differences were observed in both empathy (t = 3.155, p = 0.001, d = 0.782), and attitudes (t=3.256, p=0.001, d=0.803) when comparing control group scores (who only received the theoretical contents of the seminar) and experimental group 1 scores after receiving the full multimodal simulation (i.e. a seminar wearing an age simulation suit + volunteer interaction with an older adult). Regarding the order of educational strategies in the simulation flow, there were significant differences in the empathy scores found when both groups had received the full intervention. Accordingly, training with age simulation suits followed by storytelling provides better scores in empathy than in the opposite direction (t = 2.028, p = 0.048, d = 0.54).
Conclusions: The use of a multimodal intervention, implementing an age simulation suit and the narration of an older adult's life experiences (in this order), improves attitudes and empathy.
SOLIDWORKS Flow Simulation allows for the simulation of steady-state and transient heat transfer problems. A steady-state analysis is run to determine how the heat transfer of a system stabilizes (i.e. becomes unchanging). A steady-state solution does not inform the analyst of how much time it takes for the system to stabilize. However, a transient heat transfer analysis can be run to determine the amount of time for the system to reach steady-state.
Flow freezing allows for the specification of parameters to minimize the CPU time needed for the solution. This is done by freezing values of all flow parameters, with the exception of fluid and solid temperatures and fluid substances concentrations (if multiple substances are considered in the analysis). These parameters usually converge more slowly as compared to other flow parameters. So when flow freezing is active, the solid and fluid temperatures, as well as substance concentrations, are calculated at each iteration. The other flow parameters are assumed static or unchanging when flow freezing is active.
The periodic strategy allows the user to configure when flow freezing starts, the period it is active, the period it is inactive and optionally the specification of a manual time step to use when flow freezing is active. The start value can be set to use a unit of travel, iteration or physical time (if time-dependent is enabled in the General Settings dialogue window). The freezing period and no freezing period value use iteration as the unit. Beginning from the Start moment, the calculation is performed with freezing enabled for the interval specified in Freezing period. Then freezing is disabled for the interval specified in No freezing period. After this, the flow freezing is enabled again and so on until the calculation finishes.
The permanent strategy includes settings to denote when flow freezing starts (unit of travel, iteration, or physical time) and optionally the specification of a manual time step to use when flow freezing is active. Beginning from the Start moment, the calculation is performed with freezing enabled until the calculation finishes.
I ran two natural convection transient analyses of a heat sink with an applied heat source to the bottom surface. The first analysis was run without flow freezing enabled and using the auto time step setting. The second analysis was run using the same base setup but with flow freezing enabled. I set the physical time setting for both analyses to 1,500 seconds. The first analysis took over 17 hours to run and more than 50,000 iterations (Fig. 1). The second analysis took a little over 25 minutes to run and just over 1,100 iterations (Fig. 2). This equates to the first analysis taking over 40 times longer to complete.

Computational Fluid Dynamics or CFD is a technique that deals with the solution of fluid flow fields through numerical analysis. SOLIDWORKS Flow Simulation is a CFD software designed for the everyday SOLIDWORKS user and analyst. It provides dynamic feedback on the fluid flow and thermal performance of their products. With parametric optimization capabilities, users can automate the design and analysis process to discover the best iteration of their design within the familiar SOLIDWORKS CAD environment.
Flow Simulation enables users to simulate a wide variety of liquids and gases for different engineering scenarios. A few common applications are flow through manifolds, heat exchangers, electronics cooling and aerodynamics.

External analysis is used when we need to understand the fluid behavior around our model based on the environmental conditions. Wind turbines, airplanes, ships, heat sinks, and automobiles would all be studied using external flow analysis. In external studies, the computational domain acts as our virtual wind tunnel with boundary conditions, heat sources, and transient behavior all applied through the user-friendly setup wizard.
For certain applications, the fluid in a design might contain solid or liquid particles. The behavior of these particles and the fluid that interacts with them is critical to the function and efficacy of your system. With particle studies in SOLIDWORKS Flow Simulation, we can analyze the particle behavior and see results for erosion and accretion of the system and the particle based on material properties, mass flow rate, and other physical characteristics of the system design.
Create flow analysis projects directly on your models without importing or exporting geometry. The Flow Simulation module is fully embedded within SOLIDWORKS and utilizes the CAD User Interface to set up the analysis.

A three-dimensional, multiple-well, numerical simulator for simulating single- or two-phase flow of water and oil is developed for fractured reservoirs. The simulator equations are two-phase flow extensions of the single-phase flow equations derived by Warren and Root. The simulator accounts for relative fluid mobilities, gravity force, imbibition, and variation in reservoir properties. The simulator handles uniformly and nonuniformly properties. The simulator handles uniformly and nonuniformly distributed fractures and for no fractures at all. The simulator can be used to simulate the water-oil displacement process and in the transient testing of fractured reservoirs. The simulator was used on the conceptual models of two naturally fractured reservoirs: a quadrant of a five-spot reservoir and a live-well dipping reservoir with water drive. These results show the significance of imbibition in recovering oil from the reservoir rock in reservoirs with an interconnected fracture network.
