1'''2Created on Aug 5, 20133@author: Carl Sandstrom4This Python module is used to parse an Abaqus .inp file and store the data in the same way5as the unv2x module. In order to do so, imaginary elements on the faces of the 3D element are 6created from surfaces. The resulting element type depends on the input type and are defined 7in the method setupElement (for example, the c3d10 element are convertyed to type 118 in UNV 8and has surface element of type 42) 9'''10from FEM import *11from oofemctrlreader import *12class ElementProperties:13    def __init__(self, name, unvType=-1, edgeMask=None, faceMask=None, nnodes=-1, surfaceElementType=-1):14        if (edgeMask != None):15            self.name = name.lower() # string - name as Abaqus elements16            self.unvType = unvType17            self.edgeMask = edgeMask # 2D array expressing node masks for OOFEM's edge 1,2,..., original Abaqus node numbering18            self.faceMask = faceMask # 2D array expressing node masks for OOFEM's face 1,2,..., original Abaqus node numbering19            self.nnodes = nnodes20            self.surfaceElementType = surfaceElementType # Element type on surface21            22class AbaqusParser:23    '''24    classdocs25    '''26    27    def __init__(self,filename):28        self.file = None29        self.filename = filename30        self.FEM = FEM()31        self.ElementConfiguration = self.setupElements()32        33    def mapping(self):34        oofem_elemProp = []35        oofem_elemProp.append(oofem_elementProperties("None", [0], [], []))#leave this line [0] as it is36        oofem_elemProp.append(oofem_elementProperties("RepresentsBoundaryLoad", [],[],[]))#special element representing boundary load37        oofem_elemProp.append(oofem_elementProperties("tet21stokes", [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], [], [[0,1,2,4,5,6],[0,1,3,4,7,8],[1,2,3,5,8,9],[0,2,3,6,7,9]]))38        return oofem_elemProp39    40    def setupElements(self):41        es = [];42        es.append(ElementProperties("c3d10", 118, [], [[0,1,2,4,5,6],[0,1,3,4,7,8],[1,2,3,5,8,9],[0,2,3,6,7,9]], 10, 42))43        # es.append(ElementProperties("c3d20R", 118, [], [[0,1,2,4,5,6],[0,1,3,4,7,8],[1,2,3,5,8,9],[0,2,3,6,7,9]], 20, 42))44        return es45        46    def _read_multiple_lines(self):47        ''' Read a line from input file distributed across several rows.
