Dear all If I want to define a set of points with Dirichlet boundary conditions on a scalar unknown (pressure), are the following python script lines correct (using numpy here)?
import numpy as np DPB = 2 # dirichlet on pressure brain print('Read DIRICHLET boundary condition cranio'); # read dirichlet conditions on pressure filecranio = open('craniopdir.txt', 'r') # 'r' = read pidcranio = np.loadtxt(filecranio,dtype=int) #print(pidcranio) filecranio.close() fcranio=meshb.faces_from_pid(pidcranio) meshb.set_region(DPB,fcranio) mfpb_ = gf.MeshFem(meshb, 1) mfpb_.set_classical_fem(press_fem_order) keptdofs = np.arange(mfpb_.nbdof()) keptdofs = np.setdiff1d(keptdofs, mfpb_.basic_dof_on_region(DPB)) mfpb = gf.MeshFem("partial", mfpb_, keptdofs) How to set up that on these faces/nodes the pressure is non zero (p0= atmospheric pressure)?
