    I've tried to install VEDA in my Mac but it doesn't work....

  2. Phase contrast in Tapping mode AFM

    Closed | Responses: 0

    I tried simulation for Part II,Week-3(lecture-5 module), I used parameters as per they gave in Appendix, I am not getting the exact result as per the discussed in Lecture module.


  3. For an overlay of results, where is the button “All” located ? Also: how to select one specific simulation performed ?

  6. combining electrostatic and DMT in simulation

    Closed | Responses: 0

    Dear all, 

    I am trying to simulate the tip-sample interaction using VEDA tool. I tried it using the DMT model and electrostatic (noncontact) separately. However, I...

  7. Why and how does the choice of preferred modulus input change my results?

    Closed | Responses: 1

    Dear VEDA-Experts,

    I’m using the VEDA tool for some F-z-curve plots. If one adds Kelvin-Voigt visco-elastic force, one has to choose the preferred modulus input. I don’t...

  8. Offline installation is missing az_ddaskr

    Closed | Responses: 1

    I am trying the offline version of VEDA, and I am getting an error because the solver az_ddaskr is not found. I downloaded an older version (2.0.26) which does include the solver inside /bin,...

  9. How is the force due to Z piezo motion determined?

    Closed | Responses: 1

    Hello, Can you please tell me how the force due the Z piezo motion can be found when the Z piezo motion is arbitrary. In the VEDA manual (

  10. What causes the simulation to freeze?

    Open | Responses: 2

    I am using VEDA in contact mode. I load example 1, and use virtually all default parameters, except cantilever stiffness, which is .2 and fi, which is 23 kHz. P and I gains are both changed to...

  11. Problem with the viscous prefactor in the Kelvin-Voigt model

    Closed | Responses: 1

    Good morning,

    I have some questions about the viscoelastic Kelvin-Voigt model implemented in VEDA :

    1) In the VEDA comprehensive manual, Version 2.0, 2012, p88, I do not...

  13. How do we find Abase?

    Closed | Responses: 1

    Hello, I wish to know how the base excitation amplitude Abase can be calculated.

    Secondly, in the VEDA comprehensive manual (Febuary 2, 2009), there is multiplication of root(1 + (, a resource for nanoscience and nanotechnology, is supported by the National Science Foundation and other funding agencies.
