slow mechanism simulation
Some people here have reported that mechanism simulation run extremely slow. I had the same problem. I made a 8 wheel machine model, tires modelled as bushings and run a dynamic analysis with no movement. It took more than on hour to solve, but used only 3% of processor capacity (HP Z840, 16cores, 64Gb RAM).
I changed these settings and managed to reduce the solve time in to seconds.
1) mdo_integration_method = explicit (was automatic)
2) sim_solver_memory_allocation = 16384 (was 512)
3) mechanism_significant_digits = 16 (was 12)
I assume some or all of these have solved the problem, I also changed these:
4) cpus_to_use 16 (was 😎
5) transparency no (was yes)
Other experiencing similar promlems migth also try these, but still first thing to sort out is the model itself. There may be for instance typing errors in input values or incorrect units etc.
