FATAL ERROR: T2144
|
UNABLE TO GENERATE IMPACT ANALYSIS PARAMETERS, STATUS:
n
|
|
|
Cause:
|
An
IMPACTGENERATE Case Control command was unable to generate the nonlinear transient response input parameters required for impact analysis based on the input data provided and/or model geometry. The status codes have the following meaning:
| Code
|
Meaning
|
|---|
| 1
|
The projectile could not be located. Automated Impact Analysis requires two separate parts (the projectile and the body) that are completely unconnected. The projectile is identified by the impact grid point specified on the IMPACTGENERATE Case Control command.
|
| 2
|
The impact zone could not be located.
|
| 3
|
Unable to calculate projectile translation distance.
|
| 4
|
Unable to generate surface contact.
|
| 5
|
Other input data error.
|
|
|
|
Action:
|
Correct the input data based on the status code.
| Code
|
Action
|
|---|
| 1
|
Check that location of the impact grid point is on the projectile.
|
| 2
|
Check that the projectile translation vector points towards the impact body.
|
| 3
|
Check the projectile translation vector and position of the projectile and body.
|
| 4
|
If using shell elements make sure the projectile element normals are facing the body and vice versa.
