The function computes initial values of the given quantities at each integration point of the element from the nodal values given by the parameter nodval. Initial condition types must be the same for all nodes of the element.
| eid | - element id | |

Function assembles transformation matrix T between coordinate system defined on element and global coordinate system.
T x_local = x_global x_local = T^T x_global
direction vector denotes vector defining local coordinate axis
| x | - vector of nodal coordinates in element coordinate system | |
| tmat | - tranformation matrix T | |
| gx,gy | - vectors of nodal coordinates in global coordinate systems |
