SubscriberI am trying to run a AM process simulation.This is time sensitive. Need an ansys support engineer. but im getting an error "
 *** ERROR ***                          CP =     40.844  TIME= 12:00:40
 On the AMBU,TIME command, the recoating time value 0 is not valid. The
 command is ignored.         "Â
Here is the whole solution textÂ
