I was trying to use the type II seesaw model (generated with SARAH) in SPheno at with low scale input and got consistently error messages. With some testing I was able to locate that the problem is that the down-type quark and leptonic Yukawa couplings blow up at some point. They are OK for the first couple of times when they are called within the program.
When I took off all possible loop corrections, I did get the program run through and in the output the down-type squark and slepton masses were zero and when loops are implemented, these obviously produce the divergent results. The Treelevelmasses module computes them correctly but somewhere between the first computation and printing the output they are set to zero. Would you have an idea, where this could happen?
