Parameters of data check

This option is ALWAYS ON. This check ensures that nodal data are correct. This option is a kind of protection against possible damage of saved data.

If ON, the program searches for nodes with identical co-ordinates If two nodes of identical position are found they are merged into a single node (i.e. one of them is removed).

The value defined in Minimal distance between two points in the Mesh Setup dialogue is used for this check.

This option is effective only if parametric nodes have been defined in the project.

If ON, only the co-ordinates (calculated from input parameters) are checked. If two nodes of the same co-ordinates are found, they are merged into one node.

If OFF, the check procedure consists of two steps. First, the co-ordinates are checked. If any two nodes of the same co-ordinates are discovered, the defining parameters are check in the second step. If the two nodes are defined by means of the same parameters, they are considered duplicate and merged into one. If, however, the two nodes are defined using different parameters or different formulas, the nodes are let unchanged.

This item shows the number of discovered undefined nodes. Such nodes MUST always be corrected and therefore the checkbox is ALWAYS ON.

If any free nodes are found in the project (i.e. nodes that do not belong to any member) the user may delete them.

It is recommended to delete any free nodes unless the user has a specific reason for their existence in the project (e.g. free nodes may represent a temporary state during the definition of a complex model).

Any duplicate nodes found in the project are reported here and it up to the user whether they will be deleted or not.

It is recommended to delete duplicate nodes.

The user may decide if 1D members in the project should be checked or not.

1D members of zero length are found. If such 1D members are discovered in the project, they are always deleted.

This check goes through the model and traces double 1D members, i.e. 1D members of identical position, orientation and length. If such 1D members are discovered, the user may decide whether they should be preserved or whether only one of the identical 1D members should be kept in the project.

The program checks all additional data (e.g. loads, supports, etc.) and verifies the position of these data on members. For example, some loads might have got out of 1D member during manipulation functions. Such improper data are corrected.
