Tied Interface - Dual Mortar Method

[nima_ikm]

Dear Feap Users,

I would like to know how the tied interface based on dual mortar method is written in feap. Because, I would like to print out the mortar mass matrix (coupling matrices). As results, if you let me know what is the name of the program and what is the the name of the mortar mass matrix corresponding to the slave and master surface,I would be so appreciated.

Thanks for your kind help, in advance.

Best regards,

[Prof. R.L. Taylor]

The tangent array is computed in ./contact/tie2d/ctied2d.f -- array tanm(*,*)
