 === Wind throw ===
 Describes r6614. The calculation of wind storm damage can be activated by setting '''ok_windthrow''' to y in the orchidee.def. This module calculates the critical wind speed of a stand taking stand and soil properties into account. If the stand is managed, the damaged trees are salvaged logged. If the stand is unmanaged the damaged  trees are left on-site to decompose. The default setting for ok_windthrow is n. The damaged fractions of the stands are replanted and moved to the first age class (if more than 1 age class is used).

+=== XIOS ===
+Describes r7994. When using output_level_stomate_history=10 the model may crash. This is because we are trying to write too many data to XIOS. There is a limitation related to HDF5 version that causes an XIOS error (terminate called after throwing an instance of 'xios::CNetCdfException' what():  Error when calling function nc_enddef(ncId), NetCDF: HDF error). This kind of error is due to a combination of the number of output variables, the number of metadata variables AND the parallel writing. There is no solution except to reduce the number of variables or writing in sequential mode (that means with only 1 XIOS server or in "multiple file" mode rather than "one file" mode or by activating 2nd level server). We hope that will be solved in next releases of HDF5. The solution is to reduce the output_level_stomate_history or to manually select the variables you really need (src_xml/file_def_orchidee.xml - no need to recompile).
