I<span style="font-family: inherit;"> would like to think you for many question and comments. Especially I want to thank <span style="background-color: white; color: #222222; line-height: 18px;">Sergey Sofin, Frank Chen, Andrey Nikiforov, Markus Klein, Erwin Walker</span><span style="background-color: white; color: #222222; line-height: 18px;"> for their interest to my project and help. From the obtained mails I can conclude that <b>VESStudy</b> is used mainly for the following problems:</span></span><br />
<span style="font-family: inherit;"><span style="background-color: white; color: #222222; line-height: 18px;">- </span></span>Choice of VES electrode array and development of measurement technique.<br />
- Generation of examples for lectures.<br />
- Feasibility study for VES application to investigation of geological structures.<br />
- Solution of the inverse problem by fitting 3D model geometry.<br />
- Testing of software/methods for solution of the inverse problem.<br />
- For electrical resistivity tomography the calculations can be used for optimization of electrode positions, number of electrodes and measurement program.<br />
<br />
New version of <b>VESStudy</b> is released. In comparison with the previous version <b><a href="http://simfem-en.blogspot.de/p/vesstudy.html">VESStudy 2.0</a></b> has significant advantages. The new version together with the developed software package <b>GenModel</b> makes the generation of models much easier. Automatic mesh refinement enables to generate the models without usage of <b>Gmsh</b> program. Thus, for example, for generation of two-layer model it is enough to define four points of interface surface and to generate model by using <b>gensur</b> program. Below the new features are enumerated :<br />
1. The packet program <b>GenModel</b> for simplification of model creation was developed.<br />
2. Input of model in <b>VTK</b> format.<br />
3. Automatic mesh refinement.<br />
4. Output of medium model in <b>VTK</b> format.<br />
5. Output of electrode model in <b>VTK</b> format.<br />
6. Usage of arbitrary relief surface.<br />
7. Automatic projection of electrode position on the relief surface.<br />
8. The electrodes can be placed in an arbitrary position of the geological medium.<br />
<br />
Please feel free to ask any question.</div>

<br />
<span style="font-size: small;"><span><b>VESStudy</b> - is a tool for the BEM simulation of a vertical electric sounding study of the geological environment with an arbitrary 3D structure.<br />
The development of <b>VESStudy</b> started in 2002. Up to 2011 many tests and modifications ware performed. Initially <b>VESStudy</b> was developed as an additional module for a commercial mesh generator. In 2011 the import of <b>msh</b> files of the free mesh generator <b>Gmsh</b> (http://geuz.org/gmsh/) was implemented. This feature extension allows to use <b>VESStudy</b> as a standalone software. </span><br />
