ApplyToSources

[Ilaria Mosca]

Hi OpenQuake Team/Group,

After some years, I took the OpenQuake engine to make some hazard calculations, but I have some problems with applyToSources to the various Mmax values to a set of source zones (see a few lines of the source_model_logic_tree.xml file below).  

            <logicTreeBranchSet uncertaintyType="maxMagGRAbsolute"
                                applyToSources="1  2  3"
                                branchSetID="bs2">
                <logicTreeBranch branchID="b21">
                    <uncertaintyModel>6.5</uncertaintyModel>
                    <uncertaintyWeight>0.5</uncertaintyWeight>
                </logicTreeBranch>
                <logicTreeBranch branchID="b22">
                    <uncertaintyModel>6.7</uncertaintyModel>
                    <uncertaintyWeight>0.2</uncertaintyWeight>
                </logicTreeBranch>
                <logicTreeBranch branchID="b23">
                    <uncertaintyModel>6.9</uncertaintyModel>
                    <uncertaintyWeight>0.2</uncertaintyWeight>
                </logicTreeBranch>
                <logicTreeBranch branchID="b24">
                    <uncertaintyModel>7.1</uncertaintyModel>
                    <uncertaintyWeight>0.1</uncertaintyWeight>
                </logicTreeBranch>
             </logicTreeBranchSet>

When I include more than one ID in applyToSources I get the error message "Filename 'source_model_logic_tree.xml' line 14: uncertainty of type 'maxMagGRAbsolure' must define 'applyToSource' with only one source id"

With previous versions of OQ, I could include a list of source IDs for this type of uncertainty.

Currently, I am using version 3.32.2.

Thank you in advance for any help.

Kind regards

Ilaria

Hi Ilaria, you can resolve the issue by creating three branchsets each one applied to one source.

hi 

I have a question related to this conversation. I am also using  applyToSources for maxMagGRAbsolute (applied to one source). I have the following uncertainty models: 

• 40 sourceModels, 
• 25 abGRAbsolute (applied to 1 source model through applytoSources), 
• 2 maxMagGRAbsolute with 4 branches each (applied to 2 source models through applytoSources), and  
• 1 gsim. 

I am getting 16,000 end branches (I believe it has done 40x25x4x4 - too many for full enumeration). With the use of applytoSources should the abGRAbsolute be applied to only a single sourceModel? So should I be getting 39 + 1x25x4 + 1x4 branches?

thanks
