The 2nd argument specifies the number of state variables to track during the analysis. The number of state variables is dependent upon whether or not you desire access to constituent average stresses and strains. Allowable values for this argument are 7 or 35 for unidirectional materials and 7 or 90 for woven materials. 7 state variables should be requested unless you desire post-processing access to the constituent average stresses and strains, in that case 35 (or 90) MCT state variables should be requested. A detailed description of all 35 (or 90) MCT state variables is available in Appendix B. It should be noted that increasing the number of state variables from 7 to 35 or 90 will significantly increase the size of the results file.
