ICEM CFD Mesh Generator & Fluent
 

Respected Sir,
I am working on a FSI project, where I have a three limb pipe, which I have generated in the ICEM CFD mesh generator. when I import the geometry it shows the following error messages like "Floating point exception"
and also in fluent it shows the error message as "Pressure information is not available at the boundaries" can anyone please help me out in this to solve the problem?

Please notify me where I am lagging? i have also attached the screen shots of the error message.

Thanking You. Expecting a Reply from you.

Initialization and Boundary Conditions
 

Right after loading mesh in Fluent, it cannot show any error until and unless mesh file is incomplete or corrupt. The error you see is due to improper initialization. The statement that pressure information in not available at the boundaries imply that none of the boundaries, inlet or outlet, have pressure condition applied. Usually, outlet is given a pressure outlet condition and Fluent uses that as pressure. If the flow is incompressible, it does not really matter though.

As far as initialization is concerned, some boundary or material property is not appropriate. That's why it gives error after initialization. Check your material properties and boundary condition.

Since you are dong FSI, you have to use WB. WB maintains a settings file for Fluent. If you have setup a case once and then make some changes upstream, such as at CAD or mesh level, Fluent loads the settings file as soon as new mesh is loaded. If settings include initialization, then Fluent will do that and get into this issue. To resolve it, either you should modify the settings file or remove it completely. Removing the settings file will remove all case settings, so, you have to setup from scratch. Better alternative would be to load the case in Serial, let it give the error, then setup the case properly, and reinitialize.
