strain recorder

[Mohammadf]

Hi Dear All
I want to get strain of one of the quad elements such as quad or shellmitc4. which of quad elements can give me strain to calculate strain energy of the element? when I use the following recorder for element shellmitc4 it contains 8 columns of output. what are these columns?

nDMaterial ElasticIsotropic $matTag $E $v ;

section PlateFiber $secTag $matTag $Thick ;

element ShellMITC4 1 1 2 8 7 $secTag ;
recorder Element -file ele2.txt -ele 1 material 3 deformation ;

Thanks

In the code they are indicated as

output.tag("ResponseType","eps11");
output.tag("ResponseType","eps22");
output.tag("ResponseType","gamma12");
output.tag("ResponseType","theta11");
output.tag("ResponseType","theta22");
output.tag("ResponseType","theta33");
output.tag("ResponseType","gamma13");
output.tag("ResponseType","gamma23");

You can use it for shellmitc4.
