Hi every one,
I've faced the same problem since meshing with sHM.

But I've checked the Geometry and semicolons but I can not find the problem. Can you have a glance on it.

Thank you in advance.

[nimasam]

wow ), long post

dear javad, you missed a } in your Dictionary to close geometry cause this kind of error

[javadrasooli]

Dear Nima,
thanks a lot for your help, actually it is a simplified exercise of your book , but I have new FATAL error. Please look at this one again.

Read first line after fatal error, it seems again you miss something like }

[javadrasooli]

Thank you Nima,
I am wondering what ";" and "{}" exactly mean?
I also omitted one "{" from Geometry paragraph but I think it is now balanced. Although the first line's error is dedicating "onSlope"!
can not still understand the logic

geometry
{
    Spillway.stl
       {
        type        triSurfaceMesh;
        name        Spillway;
    regions  //not in the book
        
            onSlope
            {
                type    searchablePlane;
        planeType    pointAndNormal;
        }
    pointAndNormalDict
        {
        basePoint    (30 15 0);
        normalVector    (1 1 0);
            };  //removed ; but nothing happened
         }
    
           Upstream
        {
        type searchableBox;
        min (-18 0 -0.5);
        max (0 45 0.5);
        }

};

and the error message is :

Dear javad
there is extra } after Onslope, also you can find correct file on dvd
