Hello

Many different compilers exist for the Fortran computer language. The two main flavors of Fortran are Fortran 77 and Fortran 90. Each of these has separate compilers and the user must decide which flavor and compiler to use.

Hi

A command is used to construct a uniaxial bilinear hysteretic material object with pinching of force and deformation, damage due to ductility and energy, and degraded unloading stiffness based on ductility.

Hello everyone...

Damping that is proportional to a linear combination of the stiffness and mass. This assumption has no physical basis but it is mathematically convenient to approximate low damping in this way when exact damping values are not known.

Hello

Does anyone know about a parallel version of phrap?

Please tell me .........
