Using the Alter Command in ngspice
by Ashwith Rego 04 Oct '10

04 Oct '10

Hi >From the documentation I understand that in interactive mode, using the alter command one can change the device parameters. Does this also mean I can change the values of a resistance or voltage source in the netlist? If so how? I used the following circuit: Bridge Rectifier .options TEMP=25 V2 2 1 SIN(0 vmax 60) R2 0 3 resistance D8 1 3 1N4007 D6 2 3 1N4007 D4 0 2 1N4007 D2 0 1 1N4007 .param resistance = 10k .param vmax = 5 .end I've tried alter r2 = 10 alter r2 resistance = 10 But it won't work. How do I alter vmax or resistance? Thanks -- Ashwith J.

[Free Electronic Lab] #106: Package : rappture -- gui for archimedes

#106: Package : rappture -- gui for archimedes ----------------------+----------------------------------------------------- Reporter: chitlesh | Owner: chitlesh Type: task | Status: new Priority: major | Milestone: EPEL-6 Component: TCAD | Version: devel Keywords: | ----------------------+----------------------------------------------------- = phenomenon = Package rappture for gain a GUI interface for archimedes = background analysis = Rappture is a toolkit supporting Rapid application infrastructure, making it quick and easy to develop powerful scientific applications. At its core, Rappture is a C++ toolkit, but it has additional language bindings that let it be used in C, Fortran, MATLAB, Octave, Perl, Python, and Tcl applications. It combines numerical building blocks, such as Poisson equation solvers and iterative matrix solvers, along with a powerful infrastructure for handling user interfaces. Once you describe the input/output for your simulator, Rappture handles the rest, generating a graphical interface automatically based on your description. The resulting application is easy to deploy on the nanoHUB, so a large community of users can access it through their web browser https://nanohub.org/infrastructure/rappture/ = implementation recommendation = Don#t forget to rebuild archimedes with rappture support once rappture is under the FEL umbrella. -- Ticket URL: <https://fedorahosted.org/fedora-electronic-lab/ticket/106> Free Electronic Lab <https://fedorahosted.org/fedora-electronic-lab> Design, Simulate and Program electronics.

questions about other options

Hi, everyone, I am working on some projects, and have come up with the need for packaging. Normally you can just package something with some prefab box or tray, but I would like these to be a bit better. In that vein, I found the Cupcake CNC, which extrudes ABS to create 3d objects. It utilizes some software that is apparently free/opensource. Blender is one package, but one that interests me (being graphically challenged as it were) is Openscad. Then I thought what if we could get Openscad into this FEL package. It seems like the combination of FEL with Openscad to create packaging on the Cupcake CNC (under $1000 3D printer sold as a kit) should be a good fit. So that is my question, more or less, would it be a good fit and what would it take to get Openscad bundled? Regards, Les H

Hey Folks, Is there any antenna simulation package with FEL or any other linux based package you can suggest me?
