23418

VOLUMES DEFINE: When the parent volume is defined manually, all the linked ones are defined automatically in one step.

22073

MAP: Several algorithm improvements have been applied, concerning the quality of mesh as well as, minimization of difficulties in mesh generation.

IMPROVE

Jacobian of 2nd order solids

– The tab Fix Quality in the Mesh Parameters is now respected for the improvement. Thus, it is important to set the parameters first and then apply the function.

– Now, both mid- and corner nodes are moved.

– The algorithm performs faster and more effectively, having reduced the remaining off elements.

23663

Quality Criteria OpenFOAM: Added two quality criteria, Non Orthogonality for Solids and Growth Rate for Shells and Solids.

15738

978

Jacobian: Two options are now available. The “ANSA” which had been in use up to version 13.0.5 and the method used since v1310 is now called “NASTRAN”.

NASTRAN method

Shells: The value of the determinant of the Jacobian matrix is calculated for each integration point of the element according to NASTRAN.

The reported distortion is calculated as the ratio of the smallest value over the largest. A reported distortion value of 1 corresponds to the ideally shaped element. Negative distortion values correspond to concave elements. First triangles always have a value of 1.

Solids: The value of the determinant of the Jacobian matrix is calculated for each integration point of the element according to NASTRAN, taking into account the Integration Network [IN] field, in PSOLID property card.

The reported distortion is calculated as the ratio of the smallest value over the largest. A reported distortion value of 1 corresponds to the ideally shaped element. Negative distortion values correspond to concave elements. First order tetrahedrals always have a value of 1. For 2nd order CTETRA (10 node) elements, corner points are also considered.



HEXA BLOCK

ASSOCIATE BOXES

CHECK[Association/Model Fit]: New function to check the points, edges and faces association by defining a tolerance. The function also supports fix. In addition, the distances - between the boxes and the geometry - exceeding the given tolerance, are detected and listed.

DECKs

Lists Added the option “__order__” that displays the order of shells or solids, faces or volumes.

ELEMENTs UTIL>Match Parts: Finds the best matrix to match the source and target parts. The mean distance of all entities is taken into account for the matching (Criterion).

Run, to create the transformation matrix.

Execute, to apply the transformation.

Note, that the displayed matrix is attached to the source part (Position section in Parts Manager), as well as it can be copied manually for further use.

8356

MAT Database If a material database is read through ANSA.defaults, its path is displayed on the title of the material DB list.

23327

K_RBODY / K_JOINT: Added the options Explode/ Unexplode view in the right click list. At joints, it applies only on the K_RBODIES that this join connects, whereas for R_BODIES the explosion affects the entire model.

Script Collection

Pids2Mids : Renumbers materials so that they have the same id with the properties. In case one material is used by more than one properties, copies of this material are generated in order for the 1-1 correspondence to be generated.

CheckInclude , checks if the following are in different includes:

- Parts/Elements - Nodes/Elements - Mass/Nodes - Parts/Materials

The available fixes can be used for moving entities from one include to another.

ConvertNSMLToGEB_MT : Converts all the NSML entities of type PSHELL into GEB_MTs. The created GEB_MTs are automatically applied and they assign the calculated values in the NSM field of PSHELLs. The user optionally can delete or keep the converted NSMLs.

ConvertEnts2GEBs_GN: The script converts RBE2, RBE3, RBAR, CBAR, CBEAM, CBUSH, CGAP, or CROD elements, to GEBs_GN with interface RBE2, RBE3, or RBAR, according to user's selection. It also deletes the original elements and any entity applied on their master node (e.g. force, mass etc.). In order the script to work, the user must have a DM root directory already defined. Attention... this works in cases where the original elements are structured like "spiders" on holes, and thus the searching pattern of the GEB is always "Hole".

DoeStudy: The function has been removed.

PackModel: Creates a package of all the external files (library items) referenced by the model in a designated directory. Additionally, the user can add to the package: - The parts of the model, as these are saved in the DM - The includes of the model, as these are described in the "FullPathName" field. Under Linux, the package can be also zipped. This package can be then transferred and used as a DM path, so that all external references of the model are valid.

SplitGeoCurves: Splits selected geometric curves in a number specified by the user. At the end, the created curves divide equally the original one.

ComparisonReport: This script can be used in conjunction with the Compare Tool of ANSA Part Manager. It creates a report of the differences between compared ANSA parts. The report is in pptx format. The path of the current script must be defined in the 'MetaPost script file' field of the 'File>Export diffs' function.

PickFromList: Opens any list with all existing entities of the selected type. The user is able to select from the list. The selected entities are stored in a global variable called 'selected' for further usage. Use the popup menu of an entity using the right mouse button. Highlight effects are also available.

ShowList: It has been removed and its operation is included in PickFromList.

PointFromRBE2: This function creates fast 3D Points at the mid point of two or multi-node rbe2's

RotateElementLocalSys: Rotates the local coordinate system of shell elements either by clockwise/counter-clockwise rotation by 90 (or 60) degrees or by alignment with the local system of a selected shell.

CreateSetBuildersForMassBalance: Creates a set-builder for all the ANSA groups identified in a top-level group, specified by the user. The set-builders can be then usedfor the set-up of the Mass Balance tool in Task Manager

CheckTriasAttachedOnSpider2: Identifies trias that share a common edge with the zone of SPIDER2 spotwelds.
