material card
Altair EmployeeHi all,
I am a new user of Hyperworks, and I would like to solve a vertebral FEM with Optistruct.
Actually I have an issue with the material card.
I'd solve models with different mesh sizes and I imported the material card directly in the '.fem' file. Once, I run the simulation, the value of the elastic modulus changed.
Those are the rows:
$$ PSOLID Data
$$
$HMNAME PROP 1'property1' 5
$HWCOLOR PROP 1 11
PSOLID 1 1
$$
$$ MAT1 Data
$$
$HMNAME MAT 1'bone' 'MAT1'
$HWCOLOR MAT 1 11
MAT1 112000.0 0.3
The value I wanted was 12000 MPa. I have checked the MAT1 card and the first '1' should be the material ID (MID), but I can't understand why it doesn't keep the proper format. I had imported the elastic modulus in both ways, using the GUI and copying and pasting those rows, and I obtained the same error.
Does anyone have an idea of why it happens?
Kind regards

Altair EmployeeHi Rahul,
Thank you for your answer.
Will the solver read 12000? Does it read the 'MID' from the previous line and then recognizes that value on the MAT1 line?
Thank you very much
Yes solver will take parameter which you have defined.This is just the format which solver accept.

Thank you very much
It reads parameters by position, like a punch card
it accepts comma format, too. so you can separate parameters by ','

If you are worried about this MAT1 112000 in .fem input file.
It looks ok to me.Solver will accept the same value which you have entered.
