clearing all solutions causes initialization problem

Please login with a confirmed email address before reporting spam

Hello:
In developing a more complex chemical reaction model, I ran into a "Solution not initialized" error. Attached are two files the reproduce this error.

test_3a.mph is a simple equilibrium chemical reaction solved in 0D using the global equations physics and a stationary solver study. This produces the correct results and does so even if all solutions are cleared using "Edit>>Clear All Solutions" menu option.

test_3b.mph adds a second reaction kinetics model (mod2) and a second time dependent solver. This also gives the correct results until the "Edit>>Clear All Solutions" menu option is used and then the "Solution not initialized" error occurs. Not matter what I have tried in setting the solver "Dependent Variable" settings, I cannot get past this error.

I would appreciate some help in understanding what is happening and if there is some concept I am missing. Thanks in advance.

Peter
