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

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.

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.

Present the stress as a scalar dataset for elements of the shear panel type. These elements can only have in-plane shear stress. Whenever a shear panel element is detected, we create an additional data set with the `SHEARPANEL` qualifier. If the vis_State is used, data is reported as defined only for shear panel elements.
