Hot Clash Detection Workflow

Open Existing AutoPIPE Model

Analyze for Gravity, thermal, 2

seismic loadings

Import the AutoPIPE JSM Stress

Model

Reference in Plant Project CAD

Model

Export to JSM (File > Export, Select Load

Combination)

Open i-model Composer

Open i-model in Navigator and

perform Clash Detection

Publish i-model

3 | P a g e

4 | P a g e

5 | P a g e

Open AutoPIPE Model Open Model “PIPMALL1A_STR_FINAL_V94_SMALL_Z.DAT”

6 | P a g e

Analyze for Gravity, thermal, 4 seismic loadings Load > Static Analysis Sets

Analyze > Static

7 | P a g e

View Results – max stress = 250% at Point C03

8 | P a g e

View displacement plot for GRT1E2{1} load combination

High DY displacement = -4.286” in at C12F (Possible clash between 2 pipes)

9 | P a g e

Very high displacement of DX = 207.3 in at C02F

Any of the AutoPIPE Load Combinations can be shown displayed on screen and exported to

Bentley Navigator for check Hot Clash detection

Tools > Combinations (Select non-code combinations)

10 | P a g e

Result > Output Report

Check the maximum displacements in X, Y, Z directions as possible areas of clashes

11 | P a g e

To find other segments which give high displacements, select segments and produce a report limited to highlighted points only

Select > Connected Segments, select all groups except segment C

12 | P a g e

13 | P a g e

Export to JSM using (File > Export > JSpace Model (*.jsm)) Hint: If the insulation is displayed on the pipes then insulated deflected pipes will also be

exported for clash detection.

Select ‘Deflected Model Graphics’ and choose load combination for deflected model

14 | P a g e

JSM file is created in same folder as the DAT model file

15 | P a g e

Open i-model Composer

Select main.dgn from AutoPIPE project , User = Examples

C:\ProgramData\Bentley\imodelComposer V8i\WorkSpace\Projects\Examples\AutoPipe\dgn\Main.dgn

16 | P a g e

Import the AutoPIPE JSM Stress Model File > Import > JSpace Model (*.JSM)

Select AutoPIPE JSM Stress model

17 | P a g e

JSM Import Settings dialog

DGN Output Folder

Default folder of the JSM Stress model

Seed file C:\ProgramData\Bentley\imodelComposer

V8i\WorkSpace\Projects\Examples\AutoPipe\seed\seedautopipe.dgn Schema to Use

Select Plant Schema 6.0, From following AutoPIPE program folder C:\Bentley\AutoPIPE V8i SELECTseries3\Bentley_Plant.06.00.ecschema.xml

Note: AutoPIPE deflected stress model is to scale

Criteria TAB and Select “Levels” Task Click on 2 levels

“SEG_C_STRESS_MESH_DEFLECTED” and “SEG_D_STRESS_MESH_DEFLECTED” And drag to Set A box

Select the “Self check”

Under Rules, define a new Rule “suppress clashes within the same level” i.e. on same segment

or line number

Click “Process” button

31 | P a g e

Four (4) hard clashes are found
