Try Import->Compute(,mag(a))->Isosurface Streamline may do what you want. I assume by stream function you mean psi, where v (velocity) = -curl(psi) and the fluid is incompressible (i.e., div(v)=0). DX doesn't do that integration directly. But psi should be constant along streamlines. Also, you could evaluate the compressibility by Import->DivCurl->Isosurface(,0) Luis Miguel De La Cruz Salas <[EMAIL PROTECTED]>@opendx.watson.ibm.com on 03/13/2003 04:23:17 PM Please respond to [email protected] Sent by: [EMAIL PROTECTED] To: <[email protected]> cc: Subject: [opendx-users] stream function Hi all, I apologize to you if this question has been answered before, if so please tell me where. I have a 3D velocity field and I'd like to build isosurfaces using the magnitude of the velocity, how can I do that inside of DX?. Also, I wonder if there is a way to calculate the stream function and visualize it?. Best regards, .--. Luis M. de la Cruz S. |o_o | PhD.
