How to create a new solver?
How to create a new solver based on a standard solver (such as interFoam)?I want to add temperature and non-newtonian properties to interFoam.
Any suggestions?
Best regards. Hi
try to look at the code of interFoam in application/solver/multiphase.and you will find more informations.and the EHDFoam is a solve based on the interFoam with Electrostatic add-on.maybe usefull for you.
Regards

Thanks a lot.I'm trying to modify the solver--interFoam to overcome the problem.
Firstly,I added the temperature field in createFields.H
Secondly,adding TEqn.H and put it after the PISO loop.
Then, wmake. I got the rhcmFoam solver.
In case design ,I got the following warning:

You are probably trying to solve for a field with a generic boundary condition.

*************************************************************************** It seem that there is something wrong with your boundary definition in T.would you mind post you T file? 应该是温度T的边界条件定义问题，肯定是写T文件中边界条件中出错了，expected keyword 'uniform' or 'nonuniform', assuming deprecated Field format from Foam version 2.0. 应该是温度T的边界条件定义问题，肯定是写T文件中边界条件中出错了，expected keyword 'uniform' or 'nonuniform', assuming deprecated Field format from Foam version 2.0.
以下是U的边界条件定义
boundaryField
{
leftWall
{
type fixedValue;
value uniform (0 0 0);
}
rightWall
{
type fixedValue;
value uniform (0 0 0);
} 多谢二位，温度边界条件定义错了。现在问题解决了：）
