ERROR: Error while solving Sparse Matrix (sub 1) at Declarations4.Math.LinAlg.MatrixSparse.Solve(Vector f)

On launching the elastic analysis the error appears

Solution 1

• Verify the geometry of the model. Usually you’ll find an inaccuracy in the point coordinates of the walls. Read this article.

Solution 2

• Try to define the tie rods using a function (instead of the default option) allowing some compression in them.

Solution 3 (does not occur often)

• Computer has two processors. Read it here.
  Note: the number of processors is not the same as the number of cores!
