Hello everyone,
I’m trying to compute the Drag and Lift forces of a tumbling cylinder entering the atmosphere. From various tutorials online I found the procedure to do so with a series of filters. However, I noticed that when trying to compute e.g. Drag = Pressure*Normals_X, setting the Attribute Type to Cell Data, I do not have the option to choose for scalar value the Pressure data. Pressure is only available if I select Point Data for Attribute Type. Is this due to how I run my simulation or is there an option in Paraview to include Pressure values for the specific block I want? I am using SU2 to run my simulations and as output I have Paraview multiblock .vtm files.
Thank you in advance for your help.
Yes. It sounds like your simulation is outputting pressure as a point field rather than a cell field. That is fine. The Generate Surface Normals filter creates accurate normals for both points and cells. Just use Point Data for the Attribute Type in the Calculator filter.
Hello Kenneth,
Thank you very much for the quick reply. Glad to hear that this should work 
Best regards.
