  Hello
  
  I am modeling a complex impact problem in ANSYS's explicit dynamics. I am using tetrahedron elements and the number of elements is around 200,000. Also, the problem contains multiple contacts, crack models, etc. My CPU is a high-end one, Xeon Gold 6138 with 20 cores @ 2.00GHz with 256 Gb RAM and the license is Academic HPC.
  
  But the problem is that I cannot increase the simulation speed more than a limit. I have set the number of processor to maximum (20) but when I check the PC performance (in task manager), ANSYS is utilizing not more than 60% of CPU and 5 percent of RAM. Is there any way to make ANSYS utilize more CPU and RAM and accelerate the solution?
