Hi

Is there anyway that I use interface_springback_lsdyna for gravity analysis and have nodal deformations for the further analysis using the generated dynain file? In the keyword that I include the generated dynain, I have the initial stresses coming from springback analysis and also the nodal coordinates will be changed at time zero but in the fringe plot, I can not see the nodal deformation.

Am I doing something wrong or just I will not have access to nodal defromations at all?

 

Thanks

Hello Mostafam,

Dynain file written out after spring back analysis, contains updated coordinate system (mesh),  initial stress & strain data. So, when we use updated mesh in subsequencent analysis, deformation will be zero at t=0 sec as it is already included in nodal coordinates however you will be able to see stress & strain at t=0 sec.

Please let me know if you have any further question on it.

Regards,

Raman Babu

Hi Raman,

Thanks for the response.

Is there any way that we can include the initial coordinates and see the deformation fringe plot?

No, you can not do it using this approach. You can use dynamic relaxation based approach for preload to see the preload based deformation before the start of transient simulation
