Hi

The shape of a boundary varies with time in my moving mesh model. I need to access (during the solution - not only in

the results) the coordinates of the boundary.

My model is axisymmetric so I need to know the internal variable representing boundary radius as a function of z.

thanks

David

Hi

if you select a boundary the valuesof u,v,w are the displacements, you can use them. But it might be easier via a coupling variable, check the doc.
Depending on the frame selected you have the positions as x,y,z or Xm,Ym,Zm too, againcheck the doc

Good luck
