all entries have zero scale

Recommended Posts

Dear All:

  I am trying to use HM translator from a platform in LS-DYNA input deck to optistruct.

while i am trying to simulate it, it has error as "all entries have zero scale". 

the second questions is the load steps, how could i apply all the spc boundary and load at once?

can somebody help me for this model ?

Hi dajeet

 

If you are using any load cards which requires scale factor in it, please do provide a scale factor.

Also while reviewing your model, SPC was not defined in the loadstep. Check that too

Can you help me to check the model to make it runs with no error? just want to use this as a learning template?

using SF=1 will be ok.

thank you very much for the help.

Hi dajeet

 

If you are trying to do a simple static analysis, then Dload card is not recommended. It defines a dynamic loading condition for frequency response problems.

In your case, you can create a load collector with card image as none. Then go to BC's > create > forces and select the nodes where you want to apply the forces.

 

Once load collector for force and SPC's are made, you can create a load step and assign them under the type Linear static. This should give you the results for static cases.

If you want to analyze for a different combination of SPC's, then you have to create different load steps for the different combinations.

 

Also in your model, the Pshell property is not assigned to all the shell elements. So delete the property and create again with the same parameters.

This should work fine.
