Hi Barak,

please check for your nelx, nely and nelz. Your lelg  greater than or equal
to nelx*nely*nelz. Also, check for lelt,lelv, greater than or equal to
lelg/np.

Go to the SIZE file and make the changes. If you use lelg = 10,000, lelt =
1175, you must use np > 8 (appx 9) for your problem.

Thanks,
Tanmoy
