Hello, Can you help me? I am looking for a trick to made an extrusion along a spline with Prostar. Does someone have the solution? Tom

Use VSPGENERATE. That's exactly what it was made for. Steve

Hello there,

Using vspgenerate isn't all that intuitive since it only creates vertices. Here's a macro that I've been able to run successfully. With a little luck, it might make getting started a wee bit simpler for you...

! Macro that extrudes fluid cells from a set of shells and vertices along a spline (in the direction of ascending spline vertex nos.)

! Input variables:

*set,csex,7 ! cylindrical coordinate system

*set,typs,4 ! cell type for baseline shells

*set,typc,15 ! cell type for fluid cells

*set,spid,4 ! extrusion spline ID

*set,edis,1.0 ! extrusion distance (% of spline)

*set,ncax,40 ! axial fluid cell count

csys,csex

! Disconnect baseline shells from model and extrude ncax layers of fluid cells along the spline over a distance of edis.

Thanks a lot for the macro. It worked succesfully for me as well. Regards. Tom.
