Hi everyone!
I'm doing my first transient thermal analysis with Ansysy 12.
I have to model a section of pig iron main runner in blast furnace.
Geometry is loaded with two different convective values (one for air and one for pigiron).
Ansys can calculate temperature in each nodes. And I did it.
Now I want to change air convective value and see how long it takes to reach a stationary condiction.
I tried to use timint,off to calculate the initial condiction, but ansys crashed:
Why?
Have you others idea to solve the problems?maybe there are others commands.
Thanks in advance
