You are using the *ICFD_BOUNDARY_PRESCRIBED_VEL keyword and specifying the pulsating inlet velocity using a load curve with *DEFINE_CURVE_FUNCTION. Also, *ICFD_BOUNDARY_PRESCRIBED_VEL is&nbsp; applied to part 1 which is the inlet.&lt;\/p&gt;&lt;p&gt;The warning message is about the *ICFD_MAT ID=1 card. Could you post a screenshot of *ICFD_MAT&nbsp; ID=1 in your model? Are load curves ID 1701669236 and 41 refered to in *ICFD_MAT ID=1? Do you have these load curves defined in your model with the *DEFINE_CURVE keyword?&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/05\/03-05-2024-1714704310-mceclip1.png\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Also, what happens if you run this model with the LS-DYNA solver? Do you get an error message?
