Hi Foamers,
I added an extra equation(sediment concentration equation) in interFoam and accordingly I have modified interFoam code. while running a test case the following error comes. Please help me out. Thanks in advance.

--> FOAM FATAL IO ERROR:
wrong token type - expected word, found on line 23 the doubleScalar 1e-06

file: /home/souravhossain/OpenFOAM/souravhossain-8/run/mySuspendedSedFoam/openChannel/constant/transportProperties/water/nu at line 23.

From function Foam::Istream& Foam:perator>>(Foam::Istream&, Foam::word&)
in file primitives/strings/word/wordIO.C at line 74.

FOAM exiting

N.B. I'm using openfoam8.

it seems that transportProperties/water/nu file should have some typo or a missing entry component. could you double check the file, and/or share the file?

Thanks for your kind reply. After modifying the transportProperties file, that error has gone
phases (water air);

water
{
transportModel Newtonian;
// nu 1e-06;
nu nu [ 0 2 -1 0 0 0 0 ] 1e-06; //previously I was not mentioning dimension.
rho 1000;
}

air
{
transportModel Newtonian;
nu 1.48e-05;
rho 1;
}

sigma 0.07;
But now I 'm getting another error :

N.B. for further communication please inbox me at hossainsourav101@gmail.com through mail. I would be very happy to share my files. Thanks for your consideration.

- The new error indicates that somewhere in your modification there is an inconsistency in dimensions in one of the operations. Possibly, you need to use a "dimensionedScalar" type instead of a "scalar" type in your new code. (pure speculation without seeing the code).
- I'm afraid, I prefer the public domain for any info exchange, so that other users could benefit from it wherever appropriate - because I do 100% non-paid volunteering here (also learning from others). Thanks for your understanding.

Dear Sir, I was not aware of how to add files here. Now I am done. I have added two files
here. One file (https://www.dropbox.com/s/3dm2pet3ut...Added.pdf?dl=0) consists of my equations to be added in interFoam and other file(attached) consits of OpenFoam code. Please have a look. I am looking forward your valuable suggestion. Thanks in advance.

N.B. that dimensional error has now gone. Now another error came while running testcase:
