2 CAESAR NEUTRAL FILE VERSIONS Confirm Version of AutoPIPE (Help> About) and version of CAESAR file that can be imported. Page 2

3 TRANSFERING CAESAR MODEL TO AUTOPIPE Generating Caesar cii file in Caesar v5.0 to v5.3 Open Caesar and go to the Tools menu Page 3

4 Convert Caesar *.C2 (v5) or *._a (pre v5) Caesar file to cii Click Browse button to open dialog below to select the Caesar input file (*.C2 or *._a) Page 4

CAESAR 5.3 have an issue with $CONTROL section - where location of a variable was incorrect.

5 Note: The following error may occur when a CAESAR *.CII file is opened in AutoPIPE: forrtrl: severe (64) - Input conversion error Older builds of CAESAR 5.3 have an issue with $CONTROL section - where location of a variable was incorrect. This is a known issue - that is also mentioned in release notes of CAESAR. Install latest SP2 of CAESAR 5.3 before exporting CII file. Page 5

6 In AutoPIPE V8i v.9.4 and higher: File > Import> Caesar (*.cii), Select the cii file V8i v.9.3 and lower: File > Open > Caesar (*.cii), Select the cii file AutoPIPE V9.2 or later Select the AutoPIPE input working units Page 6

7 AutoPIPE Pre-V9.0 The matching Caesar Units file must be selected Autopipe Units can be any from drop down list. Caesar units file is *.c2u which must match the units at the bottom of the cii file Caesar units file is SIMM.c2u matches the units at the bottom of the cii file Page 7

13 Note: Typically in Caesar up to 9 displacements are combined with thermal loadings in the Caesar analysis module. Hence these are defined T1 to T9 in the CIIMAP file. But these can be changed to any AutoPIPE load case e.g. first 6 cases maybe thermal and last 3 cases may be seismic E1 to E3 as below. All displacements are imported as XTRA data > imposed displacements and not as thermal anchor movements //////////////////////////////////////////////////////////////////////// #$ IMPLDCASE U1 U2 U3 U4 U5 U6 U7 U8 U9 T1 T2 T3 T4 T5 T6 T7 T8 T9 U1 U2 U3 GR // Forces and Moments // Displacement // Uniform loads // Cut short - single load case //////////////////////////////////////////////////////////////////////// #$ IMPLDCASE U1 U2 U3 U4 U5 U6 U7 U8 U9 T1 T2 T3 T4 T5 T6 E1 E2 E3 U1 U2 U3 GR // Forces and Moments // Displacement // Uniform loads // Cut short - single load case Page 13

14 TRANSLATION LIMITATIONS Caesar neutral file format (*.cii) does not support the following: Load combinations Beams Hydrodynamic data Point Static Earthquake Factor User Nozzle Flexibility User Weld Efficiency Flanges not supported in Caesar mapped to RIGID Options or Valve Soil Spring data Wind loading data Only 9 displacements in Caesar Only 3 seismic cases (UDL g) in Caesar Page 14

15 COMPARATIVE RESULTS Sample Model has comparative Non-Linear Thermal Results within 6%. AutoPIPE has more advanced non-linear analysis engine with load sequencing and expect more accurate non-linear results than Caesar. Input Data Piping Code = B31.3 : 2006 Pipe OD = Wall Thickness = Allow Stress = 150 N/mm2 Material : Carbon Steel Support friction = 0.3 Bend Radius = 1370 (bend 70 = 2055), close miters Temp = 200C, Press = 0.25 N/mm2 2 Valves at nodes 252, 263 Caesar Page 15
