    semiconductor/component library on CST design studio 2010

    Sorry, it's already a long time I don't deal anymore with this subject. Anyway I didn't succeed with CST and then switched to Ansoft HFSS13 because it was more flexible and gave results more adherent to reality. Best regards

    Ansys 13 and 14 copling with oter Ansoft programs

    Ansys 13 and 14 coupling with other Ansoft programs Hi all, Definitely, Ansys Workbench 13 can mate with Ansoft Designer, HFSS, Maxwell and Simplorer. In its menu structure there is under options a choice for this. That's no more true in Ansys 14. Can anybody please tell if and how the...

    multisim11 optocoupler error

    What the hell! I was really blind! I watched that datasheet hundreds of times and did never mind of it! I owe you a lot of excuses. The most you search a thing, the most it's under your eyes! Best regards

    multisim11 optocoupler error

    I don't know if they have one, please note that my first effort was to warn people agaist a possible bug in Multisim, that our discussion seems to confirm. If you have a link to an Avago model, that could be the cure. That specially because, as you can see the bug is somewhat involved and...

    multisim11 optocoupler error

    Avago datasheet states the following: pin 1 : LED cathode pin 2 : LED anode pin 3 : Photodiode 1 cathode pin 4 : Photodiode 1 anode pin 5 : Photodiode 2 anode pin 6 : Photodiode 2 cathode Multisim schematic states the following: pin 1 : LED cathode pin 2 : LED anode pin 3 : Phototransistor 1...

    multisim11 optocoupler error

    Yes, you need it. I already did it before opening this thread. If you go and open that model, you'll see two transistor models instead of two photodiode models, as reported in the external schematic. But I haven't yet heard that a transistor model equals that of a photodiode. And the...

    multisim11 optocoupler error

    Hello, apparently I have stumbled upon an error on Multisim 11 optocouplers. HCNR201, a dual photodiode-single LED precision optocoupler is shown as it were made by a LED lighting two phototransistors, together with its SPICE model. The worst thing, in my opinion, is that original photodiode...

    MUltisim 11 multithreading

    That's what I feared. Thank you for your reply. Neverthless It looks me odd that a simulator, that could have lots of benefits from multithreading, yet cannot rely on this opportunity. It's like going on a balloon in an ultrasonic plane contest. Despite my 8-core, i feel like I were on a 286.

    MUltisim 11 multithreading

    Please does anybody know whether Multisim 11 can go multithread? And where are this feature's controls?:smile:

    IC 74C926(Counter and Display Driver) in Multisim

    Sorry, I see your post a lot of time later, so maybe you already solved your problem. 74C926 is a smart but old component (about 30 years old, it originally was from National), so there's very little chance you find its SPICE model. Neverthless, you may simulate it on a subcircuit and then add...

    Ultiboard11: placing SMD components on both layers

    You're right, Keith. I went not as deep as I should into help. Following your suggestion I found there's a "mirror command" to place the SMD on the opposite layer. Thanks.

    Ultiboard11: placing SMD components on both layers

    Which way, if there is one, one can place SMD components on both PCB sides using Multisim11 Ultiboard? In the case this were not possible, can you please address a suitable PCB capture/editor program? TIA

    Transformer SPICE modeling in Multisim 11

    Hi to all, Can somebody please address me to a tutor where I can learn how to create and add a new transformer model into Multisim 11? Basically I need to simulate a circuit containing a transformer I designed and built myself. Of course I know all its main parameters: number of windings, turn...

    CST studio MWS memory management

    Hi all, is there a way to tell CST Studio how much memory he can use? I'd like to reserve some for computer basic services; despite my RAM is 16 GB I ended up to virtual memory...

    A different solution in HFSS11

    Hi all, HFSS full book 10 is a very useful font of examples to understand and manage HFSS software. As I found quite different behaviour with some models of mine between HFSS and CST studio (please look at another post of mine), I decided to cross test them with a model with known behaviour. So...
