interpolate displacement result on a set of points

[Lesage,Anne Cecile J]

Dear all

 

Imagine I read a set of points that are not on my mesh nodes nor on my dof nodes

 

   file  = open("pos.txt","r")

   pos = np.loadtxt(file,dtype=float)

 

how do I interpolate my displacement results on them?

 

Something like

tracked_u = gf.compute_interpolate_on(mfub, md.variable("ub"), pos)?

 

thank you

regards

Anne-Cecile
