Can EDEM couple with the explicit algorithm of a structural solver other than OptiStruct?
I have a polyurethane screen panel. Using MotionView, I’m not able to reproduce its motion, and the panel also needs to interact with bulk material. Therefore, I am considering using OptiStruct as the solver. However, I feel that OptiStruct does not provide as many explicit analysis control options as Radioss. So I would…

How does PSIM determine the maximum allowable simulation time step?
I would like to understand how PSIM determines the maximum allowable simulation time step for a circuit. According to the PSIM documentation, the allowable maximum time step is calculated automatically and compared with the user-defined time step, and the smaller value is used for simulation. However, I have not found…

random vibration PSD moments calculation?
Hii everyone, I tried calculating PSD moments my own for damage calculation and want to compare the hyperlife tool results. I exported PSD stress vs Freq plot for an element. I used statistics in hypergraph it gave the area under curve as 5201.201 which is essentially M0. using the rectangualr integration formula given by…

CADFeko very slow at responding to mouse commands
Hello, I'm brand new to Feko, and I wanted to try it out. However I haven't managed to run a simulation because the CAD visualization isn't working. It takes on the order of 5 seconds for my mouse inputs to be registered. Bare in mind, my current CAD geometry is a single cube with a FEM model source. Why is it so slow? I…
