Founded in 2012, InSilixa is driven by the quest to democratize and drive down the cost of molecular diagnostics worldwide by leveraging its proprietary complementary metal-oxide-semiconductor (CMOS) biochip technology.\u003C\u002Fp>\u003Cp>A quarter section of a microfluidic device was created, in order to study the behavior of a soft rubber gasket under compression.  The model is fixed at the base and a downward displacement is imposed on the top surface, to squeeze the gasket.  At first glance this seems a simple problem to solve, but in fact it is actually a deceptively difficult problem to solve as it includes hyper elastic material models, large strains and contact with friction. This requires the use of a nonlinear analysis approach. InSilixa decided that this was an ideal opportunity to test the new nonlinear solution for SOLIDWORKS users, Structural Professional Engineer.\u003C\u002Fp>\u003Cp>Structural Professional Engineer enables SOLIDWORKS users to access the power and technology of SIMULIA to worlds leading provider of structural Finite Element Analysis (FEA) software. Structural Professional Engineer uses a bespoke ‘Connector’ for SOLIDWORKS Simulation Premium user to transfer both the geometry and analysis set up to Structural Professional Engineer where it can be modified if necessary and solved using the powerful high-end Abaqus solver.\u003C\u002Fp>\u003Cp>The pre-compressed finite element model, shown below, was generated using SOLIDWORKS Simulation Premium for a non linear solution. The loads and boundary conditions were easily applied as a hyper elastic material defined for the gasket. A quarter model is used as the problem is symmetric in nature and this will both speed up the solution and stabilize the model with symmetry constraints.

Once the import into Structural Professional Engineer has completed, Structural Professional Engineer can run the FEA model while SOLIDWORKS can be used for other design tasks, since the SOLIDWORKS seat is not tied up during the run.  It is even possible to shut SOLIDWORKS down during the Structural Professional Engineer run, or start it up later to perform other tasks, allowing one to multitask
