What do I need solverMaxMemory for?

SolverMaxMemory defines the maximum available memory for the stiffness matrix. It corresponds to the resolution of the model and thus determines the calculation time. Increasing this values increases the resolution and thus calculation time!

With GPU Solving, the GPU RAM must not be exceeded (most Graphics Card Boards feature 1 GB to 14 GB. If necessary, CPU can be used to solve with even more than 100 GB).
