How to obtain absolute contact value?

gslee

Hi,

 

I use /TH/INTER to obtain the contact force.

 

In Radioss help, variable group is as follows.

 

 

However, In Radioss, variable group is below.

 

Which variable is absolute value?

 

Thanks.

Hi,

if you want the total force, you you request DEF and when you plot the results in HG the total force is calculated from the component forces.

Thanks,

Thank you for your answer.

 

If I request DEF, data is FNX, FNY, FNZ, FTX, FTY, FTZ.

 

I wonder that data of DEF is the sum of absolute value of contact force on each slave node or the sum of contact force on each slave node.

 

In radioss /TH/INTER variable group, it looks like there is no absolute value.

 

If I want the sum of absolute value of contact force on each slave node, 

 

firstly, I need to obtain the contact force on each node in h3d file

secondly, calculate the absolute value on each node and sum them in HG.

 

Is it right?

 

Thanks.
