CAESAR II Version

After the Intergraph PDS data transfer is complete, you can open the CAESAR II input files. You must make the following modifications and additions:

  • Specification of material properties. Material 1 is assumed, unless a material mapping file is provided.

  • Specification of temperatures and pressures. The temperature/pressure pairs are assigned to T1, T2, T3 and P1, and P2 in order.

  • Specification of intersection types. Unreinforced is assumed.

  • Specification of restraints details. By default, only anchors and double acting supports are detected by the interface. If the exact type of restraint is to be transferred, PDS must be configured to generate the CAESAR II restraint type indicators. These restraint type indicators are shown in the Additional Notes section of the complete Neutral File interface, discussed later in this chapter. These restraint type values must be placed in HA Field 7 of the neutral file.

  • The fluid density can be transferred into CAESAR II also. Place this density value in Field 7 of the neutral file. The density value should be defined according to the density unit used in the CAESAR II units file, not in terms of specific gravity.

  • Specification of other loads. The weight of rigid elements can be transferred into CAESAR II for 3W, 4W, AV, RB, and VA type elements. For the weight of these elements to transfer, the weight value must be placed in Field 8.

  • Insulation thickness and density can also be transferred into CAESAR II. The thickness and density values should be placed in Fields 9 and 10, respectively.

In addition, review the log file generated by the interface for any anomalies. The interface sorts the elements and then ensures that diameters and wall thicknesses are defined for each element. Depending on how disorganized the Intergraph neutral file is, some assumptions made by the interface may not be correct and may require you to modify the resulting CAESAR II input file.

If the interface encounters any major problems, the process aborts and no CAESAR II input is generated. In these instances, contact Intergraph CAS Support for assistance.

If necessary, you can define a material mapping file to relate the material designations in the Intergraph neutral file to the standard CAESAR II materials. You must name this file PDS_MAT.MAP, and place it beneath the application's \SYSTEM subfolder. This mapping file contains two fields of data per line. Field 1 is 5 characters wide, and contains the CAESAR II material number that corresponds to the PDS material name. Field 2 is held in columns 7 through 21 and contains the PDS material name as it appears in the neutral file. Neither of these values should contain a decimal point.
