Version SAM 1.11.0 - - 546c4484
Features
CSAM-850 - Add the vis_SurfMeshMetric method which computes a vis_MeshMetric object to check if the mesh complies with input parameters.
Add the vis_SurfMeshMetric method. It computes a vis_Metric object that can be queried as follows:
For each element:
a. If the element complies with the input parameter or not.
b. The value of the metric.
For the whole mesh:
a. The minimum value of the metric
b. The maximum value of the metric
c. The average value of the metric
d. The compliance ratio (how many elements comply with the input parameter).
The supported input parameters are:
VIS_MESH_MINEDGELENGTH
VIS_MESH_MAXEDGELENGTH
VIS_MESH_EDGELENGTH
VIS_MESH_MAXEDGEALT
VIS_MESH_MINANGLE
VIS_MESH_MAXANGLE
CSAM-829 - Support of Ansys 2024R1
ANSLib supports 2024R1 result files.
CSAM-807 - Added support for Abaqus 2024
Format update: we now support Abaqus 2024 in CEETRON Access.

Bug Fixes
CSAM-881 - Fix performance loss during solver output writing.
Now the code while writing State results is thread safe but also avoids locking when no needed.
The thread locker were fixed to avoid blocking calls and thus recovering the performance from version 1.9.
CSAM-877 - CGNSVLib export reduce DictionnaryLookup usage
Fix performance regression in CGNS export when writing non polyhedral elements.
CSAM-873 - Fix results with several stress/strain measures in NASLib
Stress and strain results containing different strain or stress measures would lead to invalid result names and data reporting in NASLib.
CSAM-869 - Added possibility to solve sublevel problems iteratively when setting AMLS eigen solver
Added parameter PROSOLVE_AMLS_MAXEIGENDENSESIZE to decide the larger size of the sublevel matrix to be solved using LAPACK. For sublevels larger than this parameter CEETRON Solve will use an iterative approach. The iterative approach might be faster or slower, consumes lower memory and produces more accurate results. The default size is 8192.
Added value result to query the error estimated during the condensation of the stiffness matrix. In addition, users can query the PROSOLVE_CONDENSATION_ERROR that contains the largest difference between the computed eigenvalue from the eigen solver with respect to the calculated eigen value using the formula sqrt(kii)/2.Pi, where kii is the values on the diagonal of the reduced stiffness matrix.
CSAM-867 - Fixed bug in the comment line of LS-Dyna input file
Fixed a bug in the comment line of LS-Dyna input file while writing node and element sets.
CSAM-863 - Manage element with no definition in ANSLib

CSAM-861 - Manage compilation without explicit POSIX extensions definition on Linux
When compiling with GCC with only the standard C definitions enabled, compilation errors could arise due to undefined POSIX extension feature test macros. Although compiling without the GNU extensions is not recommended, we now provide a default value for these feature test macros when not defined.
CSAM-856 - Ansfwt constraint equation export
ANSFwt export: Constraint equations CE in cdb format are written by specifying first the dependent node.
CSAM-839 - VolMesh crash when less than 4 nodes are defined in the input

The general formulation for the specific case of shell rotations, allow us to find the standard shell formulation as seen in Batoz : Modelisation des structures par elements finis. Vol III, 1992.
CSAM-814 - Fix RBE3 coefficients computation
Computations of RBE3 coefficients may be wrong when all degrees of freedom available at the dependent node are not selected.

CSAM-722 - Create an option to activate the legacy mesh sizing callback behavior
Add a VIS_MESH_FUNSIZINGLEGACY option to revert the meshing sizing callback behavior to its legacy behavior, reducing the number of callbacks but decreasing the final quality.
CSAM-719 - Support of residual forces and moments in LS-DYNA result files
LS-DYNA result files written with the resplt option enabled were not correctly read. Residual forces and moments are now available in Access results.
CSAM-709 - Add model integer parameters information in NASLib meshless results

CSAM-692 - Created a new convention for Gasket Status Retrieval: from OP2 vs. VDM Mapping
A new following convention is created to show the gasket status results. if VDM_CONVENTION_ORIGINAL_GASKET_STATUS is present, then gasket status is not mapped. If not, the gasket status is mapped based on the VDM mapping.
CSAM-692 - Using the NX Nastran mapping for the GASKET status if the results are reading from NX Nastran file
Using the NX Nastran mapping for the GASKET status if the results are reading from NX Nastran file.
CSAM-684 - Fix to the unit of mass in Ansys rst file reader when the length unit is in inches
Fixed the bug in unit of mass when reading Ansys rst file if the length is in inches.
The unit of mass should be BLOB if the length is in inches.
