Creo Simulate: Run complete with fatal error

Hello,

I am trying to simulate a press-fit snap feature for validation, however when I run the simulation I get the error “Run completed with fatal error”.

Following parameters are set:

Mesh:

• Component-component interface (contact), assumed 0 friction (also attempted surface-surface contact with 0.2 COF)
• Mesh on both parts with 1mm localized elements on snap-features (tetrahedral)

Constraints:

• Prescribed 3mm movement in +Z direction on Part A (to push part A onto part B), fixed in X and Y direction
• Part B constrained in XYZ direction

Material Assignments:

• “Part A” Full-hard stainless steel
• “Part B” Xantar 22R (PC)

Analysis Settings:

Can anyone assist?

Many thanks.
