simple SHIPFLOW configuration setup

[Tobias Stein 1]

If you want to run a simple Shipflow setup for testing purposes a configuration as this should be sufficient.

 

xflow

title( title = "Shipflow_example" )

program( xpan )

vship( fn = [0.26], rn = [1e9] ) [iNFO: this is a full scale example]

hull( mono, xmauto, h1gr = "hull", fsflow, xmdens="coarse" ) [iNFO: the ships SectionGroup is called "hull" here ]

offset( file = Offsets|completeHull.exportSHF("hull_example"), lpp = 157, xaxdir = -1, ysign = 1, xori = 157, zori = 6.2 )

[iNFO: the ships OffsetGroupAssembly is called "completeHull" here, 157 represents LPP, 6.2 the draft ]

 

xpan

control( free, nonlin )

iterati( maxit = 10 )

parall( nthread = 4) [iNFO: adjust your number of coarse available]

If you want to test the viscous flow solver as well, add xchap in xflow->program and run the case with following xchap settings.

 

xchap

parall( nthread = 4 )

control( start, maxit = 10 )

 

To run a more exact case, the number of iterations in xpan should be set to 20 and for viscous calculations to about 5000. The mesh density xmdens sould be set to "fine" for accurate potential flow analysis.

Thank you very much Tobias Stein for your informative post.

I am using Shipflow for my university research purpose. My assignment is to analyze how RANS solver (xchap, xgrid) works in Shipflow.

To analyze it, I am facing problem of undersatnding command of xgrid, xchap and how to deal with them? Could you please help me in this topic?

I got some error like this. 

*** ERROR ( 401) - FILE COULD NOT BE OPENED

SYSTEM DEPENDENT ERROR STATUS NUMBER = 29

LOGICAL UNIT= 4

FILENAME=

xferrm: Error


but at the left side below the screen I got like this: 
 

*** INFO comp : results request [preparing shipflow process...]

*** INFO comp : results request [writing shipflow control file...]

*** INFO comp : results request [finished preparation of shipflow process]

*** INFO comp : running external process [C:/FLOWTECH/SHIPFLOW5.1.00-x86-rc9145/bin/shipflow.bat in design baseline]

*** INFO comp : finished results [design: baseline]

so ultimately I didn't get any output. What can I do? Any kind help plz?
