Lattice type
Altair EmployeeHello
As in the tutorial OS-T 3300 described, a line like following one has to be added in the name.fem file: + LATTICE 1 0.1 0.7 200 .
Now I would like to change the lattice type. As in the Lattice Structure Optimization file documented, four different types of lattice type exist.
'The lattice type can be controlled using the LT field on the LATTICE continuation line.'
Does this mean for example, to implement this line: '+ LATTICE 2 0.1 0.7 200 .' to get the second type of lattice type, or how and where should the LT 2 information be added?
I thank you in advance for your help!

Do you knwo why I get following ERROR message by changing the lattice type 1 to 2:
*** ERROR # 1479 *** in the input data:
Incorrectly formatted numeric data in field 7.
(If it is a character field, it should start with a letter.)
