Mas­ter or Diploma The­sis "Impro­ve­ment of the opti­mi­za­tion algo­rithm for FEM simu­la­ti­ons" (IPMS-2019-013)

Work­ing field:

The elec­tro­sta­tic MEMS-actua­tors deve­lo­ped by Fraun­ho­fer IPMS („Nano e-drive“) have com­plex geo­me­tries, that can be defi­ned through dif­fe­rent para­me­ters. To maxi­mize desi­red actua­tor cha­rac­te­ris­tics like force or deflec­tion, these have to be cho­sen ide­ally. This is achie­ved by uti­li­zing the CMA-ES opti­mi­za­tion algo­rithm.

The aim of this work is, to adapt the above-men­tio­ned algo­rithm to be more time effi­ci­ent when doing con­se­cu­tive opti­mi­za­ti­ons with simi­lar sets of para­me­ters. The­re­for results of finis­hed opti­mi­za­tion runs have to be used to pre­dict the results of fol­low-up runs to acce­le­rate them. Finally this has to be imple­men­ted in a user fri­endly pro­cess that can even be uti­li­zed by untrai­ned users.

Key Aspects:
  • Induc­tion to the basic working principle of Nano e-drive and its simu­la­tion via Finite-Ele­ment-Method
  • Induc­tion to the CMA-ES opti­mi­za­tion algo­rithm
  • Imple­men­ta­tion of the time effi­ci­ent restart algo­rithm based on finis­hed opti­mi­za­ti­ons
  • Sta­tis­ti­cal eva­lua­tion of the opti­mi­za­tion results and vali­da­tion of the algo­rithm func­tio­n­a­lity


  • Suc­cess­fully com­ple­ted Bache­lor degree or inter­me­diate diploma in Phy­sics, Infor­ma­tion Tech­no­logy or a rela­ted field
  • Basic know­ledge in the field of mecha­nics
  • Basic pro­gramming skills
  • Know­ledge of the Python pro­gramming lan­guage would be an advan­tage
  • Inde­pen­dent, goal-ori­en­ted and struc­tu­red way of working
  • Enjoy­ment of working in an inter­di­sci­pli­nary team

What we of­fer:

You will find a large net­work of experts working in an open and col­le­gial envi­ron­ment wit­hin the excel­lent Fraun­ho­fer rese­arch and deve­lop­ment infra­st­ruc­ture. We offer an exci­ting, up-to-date the­sis posi­tion in which you can bene­fit from our expe­ri­en­ced team. Our excel­lent indus­try-rela­ted rese­arch and deve­lop­ment infra­st­ruc­ture pro­vi­des you access to a large net­work of experts. You will become part of an inspi­ra­tio­nal inter­na­tio­nal work envi­ron­ment based on trust, crea­ti­vity and team spi­rit. We bes­tow upon you the respon­si­bi­lity for your the­sis pro­ject, ensu­ring you space for auto­no­mous work.

Work is plan­ned to be car­ried out in our field office in Cott­bus.

The the­sis is awar­ded over a Ger­man part­ner uni­ver­sity accord­ing to the hig­her edu­ca­tion laws of the respec­tive federal state.

Fraun­ho­fer is Europe’s lar­gest app­li­ca­tion-ori­en­ted rese­arch orga­ni­za­tion. Our rese­arch efforts are gea­red ent­i­rely to people’s needs: health, secu­rity, com­mu­ni­ca­tion, energy and the envi­ron­ment. As a result, the work under­ta­ken by our rese­ar­chers and deve­lo­pers has a signi­fi­cant impact on people’s lives. We are crea­tive. We shape tech­no­logy. We design pro­ducts. We improve methods and tech­ni­ques. We open up new vis­tas.
