[aspect-devel] Segmentation fault when referring to the functions of "class SimulatorAccess" in both depth-dependent.cc and its base model.

[Shangxin Liu]

Hi Wolfgang and Timo,

Here is the compositing material model part of my test prm file for the
public ASPECT version:

subsection Material model

  set Model name = depth dependent

  subsection Depth dependent model

    set Base model = simple compressible

    set Depth dependence method = File

    set Data directory =
/home/shangxin/aspect/data/material-model/depth-dependent-visc/

    set Viscosity depth file = four_layer_visc3.txt

  end

  subsection Simple compressible model

    set Reference density             = 3300.0

    set Thermal expansion coefficient = 4e-5

    set Viscosity                     = 1e21

    set Thermal conductivity          = 4.0

  end

end


The whole part of the prm file and the error record are also attached if
you want to take a look.


Best,


Shangxin
