Second order time scheme

[Jacques Fontaine]

The error appears only when you activate ischtp = 2 ?

Exactly and then whn I change it to =1, It works.

You can not use ischtp = 2 with all physical models (eg. RANS models - except Rij-e). In case of use ischtp =2 with incompatible options the error messages should be proper.

You could post your setup. I will check.

[fomeh]

Ok, yes I've used the standard k-epsilon, so no need to verify the setup.

Thanks again Jacques

I've just tested Rij-e with the second order time scheme but it did not work. Are you sure about it?

my xml file and user paratmeters file are attached to this post.

Thank you

Hello,

You can not use ischtp = 2 with steady flow algorithm ! You should use unsteady flow option with SIMPLEC algorithm.

[fomeh]

Yes I am sorry. It works with Rij-epsilon.

Thank you very much Jacques.
