There are several Tensor Data Types available inside this module:

  • Tensor 1 rank 1 Tensor (Vector)
  • Tensor 2 rank 2 Tensor
  • Tensor 4 rank 4 Tensor
  • Tensor 2s rank 2 Tensor (symmetric)
  • Tensor 4s rank 4 Tensor (symmetric)

Data Type Tensor1

This is a rank 1 tensor which represents a vector in 3D cartesian coordinates with length 3. Access to i-th component: T%a(i)

Data Type Tensor2

This is a rank 2 tensor in 3D cartesian coordinates with dimension 3x3. Access to i,j-component: T%ab(i,j)

Data Type Tensor4

This is a rank 4 tensor in 3D cartesian coordinates with dimension 3x3x3x3. Access to i,j,k,l-component: T%abcd(i,j,k,l)

Data Type Tensor2s

This is a symmetric rank 2 tensor in 3D cartesian coordinates which is stored as a vector with length 6. The storage order is 11,22,33,12,23,31. Access to i-th component: T%a6(i)

Data Type Tensor4s

This is a symmetric rank 4 tensor in 3D cartesian coordinates which is stored as a matrix with dimension 6x6. The storage order for both axis components is 11,22,33,12,23,31. Access to i,j-component: T%a6b6(i,j)
