Dear Jalal,

You can concentrate on MATLAB, the most famous and also reliable software to cover all of your requirements

Hi Jalal,

Check this website http://www.openfluid-project.org/index.php?page=mhydas

They may have very useful tools to help you. Also, depending on what you want to model you can try Hydrus 1D or 2D (https://www.pc-progress.com/en/Default.aspx?hydrus-1d)

Both site have free tools

Good luck

Thanks a lot Jesus, very helpful
