Is there any learning resource about implicit method in Radiosss

Altair Forum User

Hi all,

Is there any learning resource about implicit method in Radiosss? In other words, how to convert a explicit model to implicit with Radioss? Any relevant video and manual are appreciated. 

 

Thank you

Hi Roy,

Implicit Solution is RADIOSS is more to complement the Explicit Solution.  So we suggest to use it only for specific case like Spring Back.  For other generic Implicit Non-linear cases, it is always recommended and good to use OptiStruct.

Please go through the RADIOSS user guide on Implicit Structural Finite Element Analysis, where all the required detials for activating an implicit run in RADIOSS is shown.

There a few few examples (Example 2–Snap-through Roof, Example-16 – Dummy Positioning, Example-25 – Spring-back) also available in Help on implicit methods.

Hi George,

I will check this message. I want to simulate static compression test with Radioss implicit solver to verify the material parameters. Is there any similar example?

Hi Roy,

Unfortunately we don't have any tutorials or examples on compression test in RADIOSS implicit. The available examples are listed above.

Hi George,

Is there any example about quasi-static implicit example? Thank you.

Hi Roy,

You can go through Example - 16 in our Help Menu, which is a e quasi-static loading case which is resolved by RADIOSS explicit or RADIOSS implicit solvers.

I'm attaching the implicit solver model files for your reference.
