SOLIDWORKS Simulation 2019 Topology Study Intermediate Results

SOLIDWORKS Simulation 2019 now allows Topology Studies to be stopped during intermediate iterations and keep its results.  The results may not be fully optimal as the solver is interrupted before reaching convergence.

NOTE: If you terminate the solver before reaching convergence, rerunning the study will need to start from the beginning.  It cannot carry on from last iteration results.

Here is an example of a Topology study with fixtures on two faces and a force on the opposite end.  A factor of safety constraint and a half-symmetry manufacturing control has been added.

Here the solver is stopped after the 10th iteration (~12%).   You are able to view the Material Mass Plot of this iteration.

However you will see a warning in the tree that the results have not fully converged.

Also you will not be able to generate stress, strain, displacement or Factor of Safety plots with these intermediate results.  Only the Material Mass plot is available but you can still export the shape as a Graphics/Solid/Surface body.

In this case, running the study until convergence gave the following shape and exported solid body.
