Solver slowing down during solve

      Hi, I am running a tensile test on non-standard geometry. The geometry is a solid body, and has been simplified with symmetry. Have divided the object into multiple sections for easier meshing. Am a newbie at this, so not sure if the sectioning was done properly.


      Applied a displacement of 0.5mm to the holes at the clamping section, spread over 10 loadsteps. Each loadstep has min 100, max 150 substeps. Gauge length is 50mm, so the final strain is 1%.

      A good starting point rule of thumb for manual time stepping is: 25 min, 10 initial, 1000 max. Sometimes I will set the max to 10000 or 100000 during troubleshooting. nTry increasing the mesh density around the holes (guessing where the highest stresses would be).nTry setting the Solver Type to Direct.nn

      Thanks Gary, switching to Direct did the trick! The solve was completed super fast.n
