Jacobian check using macro

Altair Forum User

Hi all

I am very new to tcl and macro making and was trying to create a macro for checking the jacobian.

Using the help file from hypermesh desktop reference guide this is what i did:

 

(Documents) 72 % *createmark elems 1 'displayed'

(Documents) 72 % *createmark elems 2

(Documents) 74 % *elementtestjacobian (elements,1,0.7,2,2,0,'jacobain')

 

this gives an error of 'unknown entity type found'.

 

so i tried doing this:

 

(Documents) 72 % *createmark elems 1 'displayed'

(Documents) 72 % *createmark elems 2

(Documents) 73 % *elementtestjacobian (elements, $1 ,0.7, $2 ,2,0,'jacobain')

 

but this gave an error of 'can't read 2 no such variable found'.

 

I have done exactly what was mentioned in help file then why I am getting error?

<?xml version="1.0" encoding="UTF-8"?>

Hi Bavana,

 

Do you see 'xxx elements have selected' when you place the elements on the mark 1?

 

Looks like the elements are not selected from the display.

It works no problem for me. 

Here's my TCL script :

 *createmark elements 1 'displayed'
 *createmark elements 2
 *elementtestjacobian elements 1 0.7 2 2 1 '2D Element Jacobian'

And I got the picture:

 

<?xml version="1.0" encoding="UTF-8"?>

Dear sir

Thanks for the script you gave me. I guess the entire difference was of the brackets I was using which you didn't use. 

The script is working perfect now.

Thanks again.

Hi,

   How would I retrieve all the values in the check elems (warpage,aspect,skew, etc) in a variable

Hi

there is not direct command to return those values

you can make a tcl script to append each value into the variable

to retrieve each value, using hm_getentityvalue

or you can make a template to write them to a file, and read it into the variable

 Hi,

 

   You can use [hm_get2delemchecktestval warpage2d] to get the values.
