I am trying to simulate a wear problem. I have a hemisphere moving over a fixed rectangular surface. the hemisphere is given a periodic motion with displacement in x-direction and pressure is applied on its top surface in the y-direction. the adaptive mesh was used along with umesh motion subroutine. the code used to nodal velocity is given below
if (NODE==7)then
ULOCAL(NDIM)=0
call GETVRN(NODE,'V',VEL,JRCD,JGVBLOCK,LTRN)
where node 7 is a node of hemisphere coming in contact with a flat surface. whenever the code is run, I get 3 velocity values varying from 0.000000000000000E+000, 2.964393875047479E-323 and 6.952468044715652E-310. the values obtained is very low. I tried with 2d and 3d models, both show same problem. I am stuck with the problem.
