Have you read the MESA instrument papers?  Have you searched the MESA Community Portal, mess star.org?

You are using astero_test.mod as your starting point.  Paper 2, section 3.2 discusses the test case.  It is based on HD43985 which may not provide an adequate starting model for your case.

There is also information on the astero test case found here.

Do a search for astero if neccassary.
