Square Cylinder M1.5 blows up

Dear All-
I was trying to simulate the flow past over a square cylinder for Mach 1.5. It starts but afte a few time steps it just blows up. I have attached my .ini file. I will appreciate if you can provide any helpful pointer. sq_geo.ini

Thanks!

Try starting with a lower order e.g. order = 1, and try reducing the dt. Also, given the flow is supersonic you will need to turn on one of the shock capturing approaches (e.g. entropy filtering [solver-entropy-filter] — Documentation).

Thanks @p.vincent I did as you suggested but it still blows up.Thanks!
