<\/p>\nHi,<\/p>\n
<\/p>\n
I’m having trouble running analysis on the ciruit design tool on Ansys. From HFSS, I export s-parameters as an .sNp file, and then I open it up on the ciruit design tool. My first concern is I’m importing a 2 port network, but I’m not sure why 4 terminals aren’t begin shown; instead the ports are represented by a box on either side.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
After importing the s parameters for the two port network and putting it inside my circuit, I realized the program wasn’t recognizing the ports. After some research, I learned that perhaps importing the s-parameters aren’t enough and I need to add the port symbol on each end of the port box, seen below. The simulation ran and I was able to get a plot for s-parameters. Do you think including the port component (diamond symbol) connected to the port boxes (what I got when I initially imported the s-param data) is the correct thing to do? I ask because I’ve also gotten this warning after analysis was done: <\/span> <\/p>\n <\/p>\n Next, I needed to integrate the ports back into my circuit but the simulation doesn’t work now. It says ” Nothing to solve for LinearFrequency. Enable or clean up solution to force a new simulation.” Below is my circuit; any suggestions about what I’m doing wrong would be appreciated. I’m trying to do the same thing I did above, which is sweep for frequency and plot s-parameters. I got plots with above ciruit design without connecting any components additional components, but now for the ciruit below it isn’t working.<\/p>\n <\/p>\n Do you think it’s anything related to a license issue (I have the gui for the ciruit tool, but no solve license; however if the license was the issue, I’m assuming the first circuit design above wouldn’t even run)?<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n Also, do you know how to get the 4 terminals (2 terminals on either side) for the 2 port network (like below) because I end up connecting the capacitor back to the same node. Does the port box represent the 2 nodes? <\/span><\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n","protected":false},"template":"","class_list":["post-31402","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["3574"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["1","1","1","1","1"],"_btv_view_count":["1910"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["31402"],"_bbp_forum_id":["27793"],"_bbp_engagement":["159799"],"_bbp_voice_count":["1"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["68862"],"_bbp_last_active_id":["68862"],"_bbp_last_active_time":["2018-11-08 17:01:34"]},"test":"hgar96"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/31402","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/31402\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=31402"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
