Change or delete the materials type: Al
Hi, Currently I am modelling a combustion of methane in a cylinder chamber. When I want to delete and changed the materials type: Al to Steel material, the material type Al could not be deleted.

Can anybody assist me, how to change or delete it. If could not deleted, does material Al during the calculation effect the result calculation, since I need the steel type as the boundary condition.

Every suggestions are welcome! Regards

Re: Change or delete the materials type: Al
Hi Hassan Thanks for the responds. Before you sugested it, I have done the same procedure. But the material type ie.:Al still apears, it could not be deleted. What I want is, the Al material deleted then changed to steel material.

Now I am thinking, even the Al may not deleted from the display panel then follow the procedure you have mentioned, is the new material ( ie.: steel) will take effect?

Looking forward for the responds. Cheers!

I think you need to make sure the material is not being used by any zone - then it can be deleted or changed.
