FIDAP and temp dependent mat properties PLS HELP!!

July 13, 2006, 14:53

Hello,

I posted this message 2 days ago. I need help, I tried lots of things but still at the same point.

I am running a 2D problem which has solid and fluid elements. Fluid has a free surface. This is a simple represantation of a laser welding problem.

I can see the temperature contours and the velocity fields in the melt pool if I use constant material properties. When I try to use temperature dependent mat properties (visc(curve=2) etc.), it doesnt work. In the Fipost it says only mesh could be shown.

I generated a 3d mesh as well, exactly the same thing. Why is this happening???

I am new to FIDAP so any help will be appreciated. Please help.

Regards,

Cumali

Hi: As far as i know , your range of curve should include all the value that may happen in the calculation ,so i think your range is to narrow! Hi, i also work with the FIDAP, but i can not find any friends, so today ,it is my pleasure to know you! i hope we can communicate more in the futrue. thank you !
