Instant release EOS7R
Hello everybody, To simulate an instant release of a radionuclide in eos7r, we have to insert a no-zero value of the component in the INCON block. This value should be the mass fraction of the…

Failure of convergence in the simple 1D flow model
Dear Sir or Madam, I just built a simple 1D flow model (EOS9). I found it could not converge with my experimental parameters, however, it worked when I changed the porosity and permeability, (i.e.…
