Error message: Unable to Expand Pressure from Load Definition 1 onto Surface xxxx in Load Set 1

Error message: Unable to Expand Pressure from Load Definition 1 onto Surface xxxx in Load Set 1

(OP)
I am trying to apply pressure to a group of surfaces, where some of them are boundary surfaces. The load it seems to be applied and the results are the expected, I get however the following error message before analyzing the model

Unable to Expand Pressure from Load Definition 1 onto Surface xxxx in Load Set 1

Any help would be appreciated

RE: Error message: Unable to Expand Pressure from Load Definition 1 onto Surface xxxx in Load Set 1

Dear Alexandros,
Always before solving is better to do a PREVIEW ANALYSIS to see if FEMAP is able to write the nx nastran input file with success, if not the error in red will appear in the message area. In your case the meaning of the message is clear: you are free to apply pressure loads in any surface geometry, but if you forgot to mesh then the error ... OK?.

Best regards,
Blas.

White Paper – Your Construction ERP RFP Checklist
Selecting business software for a medium to enterprise-sized construction concern is extremely challenging in large part because most enterprise resource planning (ERP) suites originated in the world of repetitive manufacturing and are therefore a poor fit for a project and asset-centric business.
