[CFD analysis of a flow around a propeller] Multiple bodies with material assignments were detected

Project Support

I was trying to analyse a propeller with the help of this Simscale webinar but as it was rather old, several problems appeared:

  • Why couldnt i select the propeller surface for the Forces and Moments graph plotting like this image from the webinar:

  • This appeared when i tried to run the simulation: ‘‘Multiple bodies with material assignments were detected. Because this is a single region simulation, only a single body may be assigned a material. Please review your material assignments and leave only the flow volume with a material.’’

This is the link to the project.

Please help me with this. Thank you in advance.

Hey, never mind i fixed it by assigned the material to the bounding box only.
