Dear Elmer team, many thanks for your new manuals (the ones from August 2nd)! (I like the new structure of the models manual.)
Here are some mistakes I found:
1. ElmerModelsManual.pdf, page 15:
"Heat Equation String
If set to True, solve the heat equation."
This does not work. When I input this to the case.sif:
Equation 1
Heat Equation = String "False"
Active Solvers(4) = Integer 1 2 3 4
End
I get this error:
"ERROR:: CheckKeyword: Keyword: [heat equation] in section: [equation 1] is given wrong type: [string], should be of type: [logical]"
It works, if I write therefore
Equation 1
Heat Equation = Logical False
Active Solvers(4) = Integer 1 2 3 4
End
2. ElmerSolverManual.pdf, page 34:
"below unity is sometimes required to achive convergence of the nonlinear system."
___________________________________ ^
3. all manuals the keyword "Steady State" is inconsistent, sometimes it is "Steady State", sometimes "Steady state". For the case.sif the difference doesn't matter but for me it was confusing.
At least 1. should be fixed.
thanks and regards
Uwe

Re: mistakes in the Manual
Hi
Just fixed 1). Thanx! The "Heat Solver = True" and "Active Solvers(1) = 1" are btw interchangeable.
The sif file of Elmer is not case sensitive. The only thing case sensitive may be some filenames. To keep the case one can give, for example:
The type "File" will keep the case while type "String" will not. Otherwise it would be difficult to refer to files names with large caps.

Code: Select all
Output File = "BigCaseExample.vtu" ! known keyword of type File
Filename = File "MyFile.dat"

Re: mistakes in the Manual
Thanks!
If they are interchangeable, do they overwrite each other? I mean does this:
Equation 1
Active Solvers(4) = Integer 1 2 3 4
Heat Equation = Logical "False"
End
and Solver 1 is Heat means the heat solver in effect not executed?
I tired this but then I get this error:
Code: Select all
LoadInputFile: Reading base load of sif file
ERROR:: SectionContents: Problem reading logical keyword: heat equation: False
Equation 1
Active Solvers(4) = Integer 1 2 3 4
Heat Solver = Logical "False"
End
I get this error:
Code: Select all
LoadInputFile: Reading base load of sif file
CheckKeyword: Unlisted keyword: [heat solver] in section: [equation 1]
ERROR:: SectionContents: Problem reading logical keyword: heat solver: False

Hello,
Item 2 has been fixed. Several typos have been corrected in the Solver manual and the Models manual. The latest pdf is dated 17 October 2022 and is located here:
