Fixed Bugs

CSAM-1065 - Fix additional wrong qualifiers in Nastran output file stress datasets

Some Naslib stress result datasets could have wrong qualifiers when the EPSTYPE flag is not null. This flag was used for stress qualifiers while it should not.

CSAM-1062 - Fix element coordinate system from states with STATE_ROTANG main coordinate system

vis_State with a STATE_ROTANG main coordinate system may return wrong direction cosine matrices on elements that do have effectively linked rotation angle vectors.

CSAM-1060 - State without Link Cid but with IdtranCsys

When State system transformation is performed, the State object may use local coordinate system set using object VIS_IDTRAN even if there is no linked CSysId dataset.

CSAM-1052 - Resolve an issue that prevented Ansys .rst files with element centroid results from opening.

When element centroid results and other types of results were present in an RST file, opening the file would fail.

CSAM-1051 - Ansfil entity extraction from degenerated elements

ANSFil: fix potential issue when master entities (faces or segments) are extracted from degenerated element

CSAM-1050 - Avoid crash when contact property has no element

Avoid crash when contact definition BCPROP lists property Id without element

CSAM-832 - Add InterProp tests and fix Bilinear

Fix vfe_InterProp object when a bilinear curve is specified using vfe_InterPropSetNormBiLinear()

New Features

CSAM-1058 - Add information about provided third parties

CSAM-1053 - Nasfil default contact definition to Node-Faces

default global contact definition in Nasfil is changed to Node to faces

CSAM-1046 - Nasfil support of BCONTACT and BCSET per SProp

Support BCONPRP parameters FRIC and FNTOL in MSC-Nastran format Support BCONPRG parameters ERROR and BIAS in MSC-Nastran format Support BCPARA parameters BIAS, FTYPE in MSC-Nastran format Support control case keywords BCSET and BCONTACT in multiple subcases context

CSAM-1028 - Add Frequency Response category

The category attribute is now set as SYS_CATEGORY_FREQUENCYRESPONSE for Nastran Modal Frequency Response analyses.

CSAM-972 - Add bending stress and strain datasets for CBAR

Add bending stress and strain datasets in NASLib for the Nastran CBAR element (ecode 34). Real and complex values are handled.

CSAM-832 - Add interface element examples for: Gap, Inter2D, inter3D and InterProp

Add vfe exam15 and vfe_exam16 to show usage of vfe_Inter2D and vfe_Inter3D objects Add vfe exam14 to show usage of vfe_InterProp in combination with Gap element

CSAM-820 - Add support for CONNECTOR BEHAVIOR in Abaqus input file.

Add basic support for reading CONNECTOR BEHAVIOR and CONNECTOR ELASTICITY (stiffness only) from Abaqus input files in Access.

CSAM-1067 - Ansys input file export of contact pairs not containing interface elements

The export of contact pairs whose associated elements are not interface elements can now be exported to an Ansys input file.

CSAM-1065 - Fix additional wrong qualifiers in Nastran output file stress datasets

Some Naslib stress result datasets could have wrong qualifiers when the EPSTYPE flag is not null. This flag was used for stress qualifiers while it should not.

SAM 2.6.2

CSAM-1093 - Sol400 for MSC-Nastran NL generalized contact

fix NasFwt: enforce SOL 400 when exporting NonLinear Static model with generalized contact BCONTACT.

SAM 2.6.3

Mar 4, 2025 - SHA: d7ceda50

CSAM-1095 - Fix SimCenter Nastran BCTSET export with BUSRF and BSURFS

Following fixes for Nasfwt NX-Nastran export of BCTSET card are done: - Surfaces defined by shells or solids are written in separate BSURF and BSURFS blocks. - When a vis_CPair object has a SYS_NODE slave type, the corresponding surface is converted into element faces to be exported as BSURF or BSURFS. - The format issue when exporting BCONPRP with FNTOL value is fixed.

CSAM-1099 - Support MSC Contact IGLUE interface parameters

Support MSC Nastran contact IGLUE parameter in BCONPRG. Support MSC Nastran BCPARA NLGUE to de-activate Permanent Glue contact.

CSAM-1096 - Fix Altair H3DLib import resultDataBlock system when no default is defined

The H3DLib import of results may fail if there is no analysis system default in the H3D result block.

SAM 2.6.5

Mar 19, 2025 - SHA: f7e6fffc

CSAM-1095 - Nasfwt must use vis_NASFwt_write8f to write reals

Fix in Nastran input export for contact real parameters with fixed 8 characters format.
