Importing parameterized input file in CAE

Importing parameterized input file in CAE

Importing parameterized input file in CAE

(OP)
Hi everyone,

I am trying to import a model from one of the examples of abaqus (benchmark tutorial example 3.7.1). I will receive an error saying:

WARNING: The input file contains one or more data items which have been parameterized. Parameterized input files can not yet be imported into Abaqus/CAE. This occurred while scanning input file for parameterized data. The input file will not be imported

I searched in internet and found that some people suggested to open the file in text replace the parameter by the values and import again. I really didn't understand what does this actually mean? because I replaced the parameters with values but still I had issues to import it. here is the part of inp file mentioning the *parameters:

**
** MATERIALS
**
*parameter
density=1.0e-4
C10=7.64e-3
D=0
K1=996.6e-3
K2=524.6
Kappa=0.226
*Material, name=IliacAdventitia
*density
<1.0e-4>
*anisotropic hyperelastic,holzapfel, local directions=2
<C10>, <D>, <K1>, <K2>, <Kappa>
** ----------------------------------------------------------------

Would you tell me what exactly i have to do now?
Thanks a lot.

RE: Importing parameterized input file in CAE

Here I did it for you.

*Material, name=IliacAdventitia
*density
1.0e-4
*anisotropic hyperelastic,holzapfel, local directions=2
7.64e-3, 0, 996.6e-3, 524.6, 0.226

Thanks so much sdebock, it worked well. at least now i have the geometry and everything but i still have some warnings in the message area of abaqus saying:

WARNING: The following keywords/parameters are not yet supported by the input file reader
---------------------------------------------------------------------------------
*ORIENTATION, LOCALDIRECTIONS
*PREPRINT

Do you know what's wrong?

By the way do u know how can I import the parameterized inp file via MS DOS command ? If I do it in MS DOS, does it need any parameter replacement again?

Many thanks.

RE: Importing parameterized input file in CAE

Well the warning is pretty clearcut, "The following keywords/parameters are not yet supported by the input file reader".

Abaqus CAE usually lags behind on "new" things that are available through the input file. The local directions for anisotromic materials is one example, parametric input is another.

And you mean the command line? Indeed then you can just run the input file using "abaqus analysis job=.... "

Thanks for you answers

But it sounds strange, so it means that I cannot import adventitia_15deg.inp in the documnetation folder of abaqus? it's strange because it is part of the Abaqus documentation. would you try to see if you can import that model by changing removing the *parameter from the input file?

I created a job after i imported the file and the job aborted very soon which I guess is due to the warning and errors that I still see after importing the model. the error was number 5 by the way.

Kind Regards
Sepanta

RE: Importing parameterized input file in CAE

It is rare but sometimes INPs from the documentation have minor errors, so you should be careful in making sure both the theory and the predictions make sense.

Memory allocation issues cause error code 5 message to pop up. ABAQUS pre-processor expects a parameter (name of the variable) in between < > keys, not a number. This is the only error in the code snippet you pasted.

I am not sure what you mean but why not just run the .inp and import the .pes?
