Hi Roscoe,
This seems impossible - maybe you change the file rights of the .dri-file or something similar by your modification?
Or what exactly did you do?

Re: Initial concentrations
Dear Roscoe,
Have you already been able to open and run unchanged example driving files by using the MICpad editor? Then it should also work with the .dri-file which Ralph has created for you.
Best wishes

Re: Phase determination
Dear Rosco, In the example input file which you append, the nature of the "austenite" phase is only reflected indirectly by the phase data and phase interaction data which are provided in the input file. That means, it could be any phase with the given properties, and without knowing the purpose of ...

Re: stress
Dear kaiyang, It seems that the only problem is the extremely high elastic strain of 2% which you apply in z-direction. This leads to numerical problems with the interfaces, in turn somehow leading to grain boundary adhesion at the bcc particles, and very fast movement of the fcc/fcc-grain boundarie...

Re: stress
Dear kaiyang, Welcome to the MICRESS forum. Without additional context it is not possible to understand what happens hear. You should provide more information about your material and setup, and what you intend to simulate. Optimal would be to also attach or paste your input file here. Just judging f...

Re: Reading GES5 workspace
Dear waltergarcia, Welcome to the MICRESS Forum! When you define 3 dissolved element in MICRESS, you essentially assume to have a 4-component system, because you need to add the matrix component. On the other hand, when you open a .GES5-file and MICRESS tells you that it contains 3 Elements, this nu...

Re: Eigenstrain
Dear Jane, please take care that there should be no underscore "_" in the keyword. In MICRESS Version 7.0 the syntax for stress coupling was stressUx: uncoupled (i.e. no effect on driving force) stressCEx: chemo-elastic coupling (i.e. elastic effects on driving force for phase transformation) stress...

Re: Eigenstrain
Dear Jane, If you use stress coupling (stress_mc* or stress _ce*), then elastic stresses may have an effect on the phase transformation. You can see this effect primarily as a mechanical driving force (.dGsp output). The effect can be strong or weak, depending on the size of this driving force (abso...

Re: Eigenstrain
Dear Jane,
While for the "normal" molar volume all elements are counted, the "mechanically relevant" molar volume only refers to the lattice-building (=substitutional) atoms. If coupling to database is used, the distinction is made automatically.

Re: Eigenstrain
Hi Jane, 1.) There is none ;) 2.) Volume is transformed in the following way to obtain the eigenstrain ε of phase α. Here a is a lattice constant, and β is the reference phase. a = ( Vm ) 1/3 ε(α) = [a(α) /a(β)] - 1 However, if you are using direct input of eigenstrains, you should essentially speci...
