SAM 3.1 latest [Mar 31, 2026]

SHA: c3503f96

Fixed Bugs

CSAM-1618 - Fix Permas reading for complex data across sections

When reading complex values on entities with more than one section, the provided results were wrong. Expected changes:

  • Results with complex values and more than 1 section.

CSAM-1560 - Fix support of distributed orientation definitions in Abaqus input files for shell sections

The support of shell sections with distributed orientations for Abaqus input files was not fully functional. The use of Solve on the generated Model could fail.

CSAM-1522 - Export ordered entities in CMBLOCK Ansys command

When exporting Ansys .cbd files, Access now makes sure that the entities are ordered in the CMBLOCK command. Remove access violation that occurred when reading material orientation vectors with double precision. Expected changes:

  • Exported CMBLOCKs now contain ordered entities.

CSAM-1411 - EnSight result file cannot be opened

EnSight result file sets with a badly formatted FILE section in the .case file were failing to be read.

New Features

CSAM-1531 - Add support for reading the DBLOCK command from Ansys input decks

Access can now read the DBLOCK command with basic formatting (DOF constraints using non-tabular input). Expected changes:

  • Additional datasets might be created from BLOCK commands when reading Ansys .cdb files.

CSAM-1519 - Support to read Ansys 2026 R1 result files

Support to read Ansys 2026 R1 result files.

CSAM-1518 - Support to read 2026 Abaqus odb files through Access

Support to read 2026 Abaqus odb files through Access.

CSAM-1459 - Support for Ansys keywords CMSEL, SF, NSLE and SFE:FSIN

Add support for Ansys keywords: TREF, CMSEL, NSLE, SF and SFE:Label=FSIN If the Ansys input contains a surface load defined using SF or SFE with the label FSIN, representing the “field-surface interface number”, this surface will be translated into a vis_Cpair object on the master side. The surface identifier is stored in the CPAIR_PID parameter. When TREF is read, it is used as the default for materials that do not have a local REFT definition and is stored in MPROP_TREF.

CSAM-1414 - Add support for COMPACT format for the EBLOCK command in Ansys input decks.

Add support for reading ANSYS COMPACT EBLOCK format in CDB files. Add support for reading “keyo” as an abbreviation of the “keyopt” command. Expected changes:

  • Different size of the PROP.INT.T dataset.

CSAM-1135 - Export Abaqus input with material name when available

When exporting the model to the Abaqus input format, materials are now defined using their own names when available. Expected changes:

  • Exported Abaqus files will now use names other than MID1, MID2, … when this information is available in the vis_MProp object.
