$inplanestrainrel

$inplanestrainrel is the command to relax the in plane strain x' and y' by a factor_kx' and factor_ky'

The format is

$inplanestrainrel
Str_x'  Str_y' 
Str_x'  Str_y' 
Str_x'  Str_y' 
Str_x'  Str_y' 
...
...
...  total N layers

Str_x' and Str_y' are values between 0 and 1.0. The reason to use this command is to model if the layer's strain will relaxed during growth. Therefore, the strain may not in the idea condition. Therefore, the in-plane strain will be relaxed by this factor. However, since another command $Assignkpstrain can be used. Usually can directly assign the strain with this command. So this command may not be needed. This command only works when $calculatekp is used and Weighting is not equal to 1. In this case, the program will calculate the strain in the solver. Then this function will be used.

Currently, the solver goes with DDCC GUI where these parameters are calculated before feeding into the ddcc solver. Therefore, this command is less used.
