April 2026

The release notes for the upcoming release are:

New features


General modifications

  • Performance

    • Performance of the PARDISO solver was noticeably improved, reducing solve time by up to a factor of 3.
  • Constitutive models

    • Barotropic elasticity was modified such that for void ratios smaller than \(e<10^{-3}\) the pyknotropy feature is deactivated
  • Output

    • Stress and Strain output are now requested via stress and strain, respectively. The old keywords S and E are deprecated (backward compatibility is maintained).
    • More detailed information for cutback reasons during automatic time stepping reported in statistic (.sta) and message (.msg) files

Resolved bugs

  • Resolved bug for *Equations where the coupling terms between two constrained degrees of freedom are inactive in the model

  • Resolved bug for hypoplastic/Sanisand contact models.

  • Linux versions: import of random fields from csv-files fixed
