[Mesa-users] Help regarding MESA

[ABHIJNAN KAR 20064]

Thanks for the repyl and sorry for posting questions in hurry.The run is showing error before even the mass transfer could start, I can see from the parameter values during the run that the M dot is still 0 and the masses are unchanged while the error occurs(dt<min_timestep_limits).And yeah, I removed the other hooks for angular momentum loss but for pulsar evaporation wind I am using that.Previously it was giving results correctly in accordance with paper (which i am reproducing).But now I can’t figure out the error.I have moved this out of test suite in a seperate directory and running it.
