 Reporter: Artectek
   Status: new
Milestone: ET_2022_05
  Version: ET_2022_05
     Type: bug
 Priority: minor
Component: EinsteinToolkit thorn

Changes (by Artectek):
I try to run a double neutron star sim,using a cold eos table,but i keep running into nan for months,the par file and the output and err file are in the attachments.please give me some hints on where could be going wrong,I really have no clue.

there are other sim i used,but the result are the same,usually it started normal,everything looks fine,the center density the stable,the rotation looks ok,but later on,just when the matter from two stars started to interact with each other,something always happen,either

nan on the start of the interaction,or nan in the process of [merge. At](http://merge.at) first i thought maybe it became a blackhole,but the i checked the center density,it did not show signs of continue increase,often it just running normally and nan just happened.

i can provide the eos table,or anything you need,please,i just need some hint,i tried everything i know,i am drying out here
