Meshing during simulation

Altair Forum User

Hello,

I would try to do a incremental forming simulation with Radioss; during simulation, unfortunately, mesh has high distorsion. How can I do to set-up the mesh variation during simulation?

thanks

Could you share us .out file of the run?

Hi Rahul,

I can share .out file but, whereas it's a university project I would like to know how I can do it, so I can explain it to other member of the project.

Thanks for your availability.

Please share 0000.out and 0001.out files

From the .out files it is clear that time step has drastically reduced and the run was terminated. Check the interface 1.

 

When the time step is reducing during the run :

 

Check which object is responsible for the low  time step (.out file). It can be an element, a node or an interface.

>For an element, check the related material.There must not be an error in the units system that this data is given in. check the element size also.

>For a node, check the characteristics of connected elements. If the node is on the master side or the slave side of an interface, this interface must be verified.

>For an interface, the gap of the interface must be verified if some failure happens on the master or the slave side of the interface.

Hi, thanks George for your reply; I would like to say if there is a possibility to implement in Radioss a remeshing 2D tool when the mesh has large distortion.

Thanks
