Calculating Drag Force

thread810-274543

Calculating Drag Force

Calculating Drag Force

(OP)
Is there a way to integrate the resulting pressures from an algor static fluid analysis over a surface to obtain the a reaction (drag) force?  Possibly a sum of nodal reaction?

Any input would be greatly appreciated...

RE: Calculating Drag Force

Pressure distributions can be applied to surfaces using surface variable loads.  Surface variable loads have to be continuous functions.  If you require changes of function to describe, say, wind pressure around a cylinder or tank which needs 2 functions, then the surface needs to be split.  I have asked Algor to add if statements to the surface variable load  facility to give more control.
