Hi! I am solving a problem involving mass and enthalpy source term (sorsca.f, sorent.f,fluinj.f) but I always got the warning like this *** WARNING # 532 *** SORMOM ACTIVATED BUT NOT USED *** WARNING # 529 *** SCALFN ACTIVATED BUT NOT USED

I check my model repeatedly, really I didn't activity the momentum or other subroutine. does anybody can explain it or tell what problem is? I will feel very grateful. thanks Juliet

You are half way there, in that you have activated the subroutine in prostar, however you now need to compile the coding into your executable. You need to have a subdirectory called "ufile", which should contain sormom.f etc.. When you run "starlink", answer "y" when it asks if you have any user coding.

Hi!

Thank you alex. in fact i just need activity the mass and enthalpy source term. i know the step of doing that. and i make the subroutine of sorsca.f, fluinj.f,sorent.f. according to the step that you mentioned , but for my calculation i needn't modify momentum equation, so i didn't activity the momementum source term or other subroutine. i wonder why i got this message from star when i calculated. maybe after i activity mass and enthalpy, the momentum should be activity. but i really don't need it. i once use this subroutine to other model,but didn't appear this warning, why? help!

thanks lots
