I am solving a pure conduction problem in solid, And I test the results in both ANSYS Mechanical and Fluent too.<\/span>

I have to share something.<\/span>

ANSYS Mechanical-<\/span><\/p>\n

<\/p>\n

\"\"
1) Gives very good\/appropriate\/relevant result in automatic mode.<\/span>
2) I am not familiar with scripting\/command in the workbench Mechanical (WM). So I switch to Fluent and easy to use UDF for my model.<\/span>
3)Very less access of solver through GUI in workbench Mechanical. And I also don’t know how to check convergence plot (like Fluent shows at every iteration), How to put Boundary condition varying with solver variable, etc. in WM.<\/span>


Fluent-<\/span>
1)It’s very hard to let the solution converged at every time step in long heating time (1 hour) and reports don’t change much with iterations. So it gives bad result comparing to WM.<\/span>
2)Fluent has very much access to solver through GUI and can set so many things easily about convergence, reports, etc.<\/span>
3) I think UDF in Fluent is relatively easier than workbench Mechanical scripting or APDL command.<\/span><\/p>\n
